GM has confirmed plans to build another electric vehicle at the same Orion Township, MI factory where it currently manufactures the Bolt, as well as test autonomous vehicles for Cruise. We don’t have a name or potential release date for this next EV, but it will use the same BEV3 platform underpinning the recently announced electric Cadillac on the way.
Dash cams are already essential in many countries because of scam artists who try to create accidents so they can sue you. They’ve also proven useful for catching cars flying into buildings, or the occasional meteor, as happened in Thailand and in Russia, all thanks to dash cams in the right place at the right time.
But while auto con artists aren’t as common here, recording your excursions is a reasonable precaution to take—especially if you’re driving professionally. And even if you’re not, you may unexpectedly appreciate using it to chronicle your vacation travels—or tap into your smart home, as we recently tested with an Alexa-enabled dash cam, the Garmin Speak Plus.
March 22, 2019: We just reviewed Z-Edge’s T4 dash cam (available on Amazon), which kind of broke our hearts because it’s almost the full package. It offers impressive design and construction, including a 4-inch touchscreen and an easy interface. It sports high-resolution 1440p front and 1080p rear cameras, both of which record some of the best video we’ve seen. We also like the parking mode, which turns on the camera if something (like a thief or a bumper-basher) trips its g-sensor. But it doesn’t have GPS, and that’s a bummer. Read our full review.
Best front/rear dash cam
The A129 Duo is easily our favorite budget dual-camera dash cam (available on Amazon), with superior 1080p day and night video from both the front and rear cameras. It holds its own against far more expensive duos from Thinkware and Blackvue. Aside from the somewhat unwieldy rear cam cable, it’s all goodness, all the time. Read our full review.
Best budget front/rear dash cam
The CDR 895 D Drive HD is by far the cheapest dual-camera system we’re aware of (available on Amazon), even when you add $50 for the option GPS mount. Its controls and interface are top-notch, and day video from the 1080p/160-degree front camera is excellent. For all the details, read our full review of the Cobra CDR 895 D.
Best front dash cam
The 612GW (available on Amazon) made quite the impression with its touch display and extra-detailed 2160p video. It’s a fantastic dash cam overall, though the inferior low-light captures will be an issue for some. Read our review.
Garmin’s Speak Plus dash cam (available on Amazon) deserves mention because it’s the only dash cam (other than its predecessor, the Garmin Speak) that can be controlled using Amazon’s Alexa smart assistant. You can also, of course, ask Alexa to do other things around your home while you’re in the car. You’ll need to keep your smartphone handy to enjoy all the features, though. Read our full review.
Best budget front dash cam
The Vantrue OnDash N1 Pro (available on Amazon) is our new favorite low-cost dash cam. It’s compact, light, relatively inexpensive, takes good video under all conditions, and has a real battery to keep running if the 12-volt fails. Because we recommend GPS for legal and travelogue reasons, I’m going to talk about it as if the $22 optional GPS mount were part of the deal. If you’re smart, it will be. Read our full review.
What to look for in a dash cam
12-volt power: All dash cams use 12-volt power sources, and the majority of them grab it from the auxiliary power outlet (also known as the cigarette lighter). But that power disappears when you turn your car off. Outliers like the Owl and PureCam use OBD-II connector for constant 12-volt power, and OBD II to USB power cables are now available separately as an alternative to hardwiring kits that draw constant 12-volt power from the wiring harness.
Battery power: A battery that will keep the camera recording after an accident is important if you want to be sure you record an entire incident when 12-volt power is lost. If run time is sufficient, it also allows you to record for a while with the car turned off. Supercapacitors, though they may sound like an improvement on batteries (in terms of recharge cycles and operating temperatures they are), don’t offer much recording after the fact, and in some cases—none at all.
Continuous looped recording, so you’ll never lose fresh data (Of course, older data will eventually be overwritten.)
Incident recording triggered by impact (G) sensors
Continued recording when power fails so that you can be sure to capture all of an incident. This requires a battery or large supercapacitor. The camera should have a setting that allows you to set how long the camera runs off 12-volt before shutting down.
A decently wide field of view: You’ll see cameras with as little as 90 degrees’ field of view, but you’ll catch more of what’s around you if you go for 120 to 140 degrees. Some cameras offer 160 to 180 degree lenses. Note that the wider the field of view, the more fish-eye distortion there is, and more processing is involved to compensate.
Day and night video recording (night quality is a big variant)
MicroSD card storage. Pricier dash cams bundle a storage card. Some come with larger cards, and some budget models come without. There are often bundles available with the card. One camera, the Owl opts for hard-wired internal storage.
GPS: This feature could be the tipping point if you use your captured video to resolve a dispute. GPS should either watermark or embed your video with geographical coordinates,. GPS will also automatically set the time in better cameras.
Parking monitoring: This simply means running the camera where you’re not in the car. We have reviewed cameras (VaVa) that have a battery large enough to monitor the car (at a reduced video frame rate) with the 12-volt turned off. But most cameras require that you hardwire to a constant 12-volt source.
Dual-channel support: This is what you’ll need if you want to run both front and rear (or interior) cameras, though it’ll involve more cabling (and cost more overall). Only a few models we’ve tested have it: The Thinkware F770 (available on Amazon), for instance, though the rear camera costs an additional $80; and the Cobra CDR 895 D Drive HD (available on Amazon), which gets you into dual-channel video for a measly $200—rear camera included.
How we test dash cams
Few people are as well situated geographically as I am to test dash cams. Within two blocks there are major four- and six-lane thoroughfares, numerous bike lanes, joggers, dog walkers, oblivious ear-budded pedestrians, and a major bus nexus serving both public and private coaches. The opportunities for near-accident are endless.
For every dash cam, I mount it in my car, judging the ease and convenience of doing so. Tip: Many dash cams rely on adhesive for mounting to your windshield. Hot conditions can make it next to impossible to remove the film that protects the adhesive. Remove the film in a cool environment, or place it in the fridge for a minute or two before installing it.
I put each dash cam through several days’ and nights’ worth of driving, recording video and judging the image quality. All the dash cams I’ve reviewed in the last couple of years take good daytime video. However, night video is often plagued by murky shadows and headlight flare. That said, quality is improving rapidly with the introduction of new sensors. Take a close look at the night shots in each review.
I try all the features: Buttons, display controls, apps. Aside from rear-view support and GPS, the most salient differences between the products are the interface controls and extra features, such as the lane departure and collision warnings that you get with some models. I try them…and I turn them off. In practice, they usually tell me I’m changing lanes, in heavy traffic, or have just been cut off. Additionally, the collision warnings generally come too late to do anything but distract you at exactly the wrong time.
The most pertinent improvements as of late are HDR support (High Dynamic Range, for greater detail and contrast) and the aforementioned better night video processing. A warmer color palette is also apparent in many newer cameras. Some cameras definitely stand out, but nearly all the dash cams I’ve seen will capture sufficient detail during any daytime metal-on-metal encounters you’re unlucky enough to experience. Again, pay attention to the night video shots—that’s the big differentiator.
What’s next in dash cams
Dash cams have plenty of room to evolve. As nice as dual-channel is, there’s talk about true 360-degree video. Check out TechHive’s review of PowerDVD 16’s 3D playback to see how compelling that can be.
As I predicted at last writing, someone finally produced a dash cam that uploads to the cloud when an incident occurs—the Owl Car Cam. Additionally, it hard-wires by default to the OBD connector for easy-install, 24-hour surveillance. It has some foibles, but read the review—it’s the wave of the future, at least for the high end.

This is not a piece of serious news. I don’t think it’s a huge indictment that Huawei CFO Meng Wanzhou — who’s currently under house arrest in Canada while she fights extradition to the US — happened to be carrying a 12-inch MacBook, an iPhone 7 Plus, and an iPad Pro when she was taken into custody.
…we do live in the year 2019, when most tech companies don’t require their employees to use company-issued electronics for personal use. Microsoft and Google employees sometimes walk around using iPhones and MacBooks and iPads. I’ve seen it. It’s not a huge deal.
Here’s what gets me, though: We at The Vergecalled Huawei’s Matebook Pro X the single best laptop you can buy right now. Does she just not like Windows, perhaps?
She does have good taste in Huawei phones, though. Court documents show she was also carrying a Huawei Mate 20 RS Porsche Edition, also known as the luxury version of a phone we called “the best America can’t get.” As to the iPhone 7 Plus, it’s hard to speculate — but one could generously imagine it might have served as an excellent mobile hotspot during her time in North America.
Tesla CEO Elon Musk argued Friday that his Twitter use did not violate a settlement agreement with the U.S. Securities and Exchange Commission and that the agency’s request to have him held in contempt is based on a “radical interpretation” of the order, according to court papers filed in Manhattan federal court.
The SEC has asked a judge to hold Musk in contempt for violating a settlement agreement reached last year over Musk’s now infamous “funding secured” tweet. Under that agreement, Musk is supposed to get approval from Tesla’s board before communicating potentially material information to investors.
Musk contends he didn’t violate the agreement and that the problem lies in the SEC’s interpretation, which he describes as “virtually wrong at every level.” The filing also reveals new details about the settlement negotiations, notably that the SEC sent Musk a draft agreement that would have required him to obtain pre-approval for all public statements related to Tesla, in any format.
Musk and Tesla never agreed to those terms. Instead, Musk says the agreement requires him to comply with Tesla own policy, which would require pre-approval for “written communications that contain, or reasonably could contain, information material to the company or its shareholders.”
The barbs traded via court filings are the latest in an escalating fight between the billionaire entrepreneur and SEC that began last August when Musk tweeted that he had “funding secured” for a private takeover of the company at $420 per share. The SEC filed a complaint in federal district court in September alleging that Musk lied.
Musk and Tesla settled with the SEC last year without admitting wrongdoing. Tesla agreed to pay a $20 million fine; Musk had to agree to step down as Tesla chairman for a period of at least three years; the company had to appoint two independent directors to the board; and Tesla was also told to put in place a way to monitor Musk’s statements to the public about the company, including via Twitter.
But the fight was re-ignited last month after Musk sent a tweet on February 19 that Tesla would produce “around” 500,000 cars this year, correcting himself hours later to clarify that he meant the company would be producing at an annualized rate of 500,000 vehicles by year end.
The SEC argued that the tweet sent by Musk violated their agreement. Musk has said the tweet was “immaterial” and complied with the settlement.
