Comma.ai makes your car semi-autonomous for $999

At TechCrunch's Disrupt conference in San Francisco, Comma.ai founder George "Geohot" Hotz announced the launch of the Comma One semi-autonomous driving device. Hotz said at the conference that his company has worked on the Comma One for about a year, and it will be available at the end of the year for $999 and a $24 per month subscription fee. But aside from the reasonable price, which TechCrunch points out is possible thanks to off-the-shelf components, the appeal here is that it's an add-on to an existing car that can be installed at home by the car's owner. This gives people with normal cars the opportunity to have semi-autonomous features without having to buy an entire vehicle... that is, if you have a Honda or Acura with lane-keeping assist, since Comma One is currently only compatible with those vehicles. It remains to be seen if the company will add more vehicles to the list over time. The device is roughly the size of a large cell phone or aftermarket navigation system, and it has a screen on the front and a pair of cameras on the back. The computer combines information from the device's cameras and the car's radar sensors to understand what's happening and how to respond. Hotz explained at the conference that this system is similar in capability to the Tesla Autopilot system, and will be able to complete a drive, start to finish, without the driver having to touch anything. He did however emphasize that the driver must still pay attention in the event something goes wrong, comparing the experience to watching a young student driver. Hotz told TechCrunch that the device should start shipping at the end of the year. He also said that owners of compatible Honda products in the San Francisco area are eligible for beta testing, and can get involved by emailing him at george@comma.ai. So if you've been pining for a semi-autonomous vehicle of your own, but couldn't spring for a Tesla, you won't have to wait much longer. We should point out that we don't know yet how well the system works, though we hope to find out soon. Related Video:

Acura recalling nearly 20k new MDX crossovers over AWD driveshafts

Acura is recalling nearly 20,000 of its 2014 MDX crossovers fitted with all-wheel drive over driveshaft concerns. The affected vehicles were built between May 6, 2013 and October 14, 2013, and have bolts that attach the driveshaft to the transmission that may not have been tightened properly.
Needless to say, an improperly secured driveshaft could lead to a number of problems, including everything from excessive drivetrain noise to full driveshaft detachment, a condition which could result in a loss of power and crash.
There's been no reports of accidents, injuries or deaths relating to the driveshaft issues. Acura will begin notifying all 19,197 owners in question of the recall, and will request that they report in for repairs, which will consist of tightening the driveshaft-attaching bolts. Scroll down for the official bulletin from NHTSA.

Acura TL gets its top chopped

The roofless Acura TL you see above is a product of Newport Convertible Engineering. No stranger to taking the lids off of Acuras - and a bunch of other cars, like this Jaguar XJ and this Toyota FJ Cruiser - NCE says it was the first US coachbuilder to produce an Acura NSX convertible.
NCE says the conversion takes about six weeks to complete, comes with a five-year warranty from the supplier and doesn't void the original warranty from Acura. On top of that, the interior fitments like sun visors, trunk space and rear seat belts all remain unaltered. Customers who are absolutely against the B-pillar can have it removed, but NCE says "The vehicle will be designed differently without the center bar."
To our eyes the TL looks pretty all right without a roof, and with stripes. NCE will shortly be preparing convertible versions of the 2013 Range Rover Supercharged Autobiography, Porsche Cayenne and Cadillac XTS. For Acura owners, there's a press release below with information on NCE if you have a TL and an urge to go way beyond the sunroof.
