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 to roll out NSX Prototype for Mid-Ohio IndyCar race

Acura will tease us yet again with its next-gen NSX when it makes an appearance at Mid-Ohio Raceway before the circuit's IndyCar race early next month. To be fair, the car's in-motion debut won't take the form of a production model - that's still a ways off - the vehicle will be a prototype. It'll be sporting custom graphics and an eye-catching paint (wrap?) job to draw the attention of the spectators, but really, we just want to hear this thing rounding the legendary road course at full chat.
The NSX prototype doesn't look to be much different from the various showcars we've seen over the last couple of years, with the same mid-engined, hybrid V6 power and all-wheel drive all present and accounted for.
The display will take place before the Honda Indy 200 IndyCar Series on August 4. The race itself starts at 3:00 pm and will be shown on NBC Sports Network.

Honda, Top Gear working on 130-mph lawn mower

We're not even sure they've got a blade of Kentucky Bluegrass to cut, but the folks at Top Gear have gone ahead and started building what will become, if they're successful, the world's fastest lawn mower. Actually, it appears Top Gear is not doing much of the design and assembly work at all, instead having solicited help from experts at Honda and Team Dynamics, which oversees the automaker's touring car efforts.
What the three are working on is a riding lawnmower with a 110-hp engine that can reach 60 miles per hour in four seconds and trim turf at speeds up to 130 mph. If they succeed, such a maximum velocity would put them well ahead of the current record for the world's fastest lawnmower, which is 96.529 mph set by Bobby Cleveland and his Snapper race mower at the Bonneville Salt Flats in September of 2010. Top Gear hasn't said whether or not it will officially go after Cleveland's record, but the build will be featured in an upcoming issue of the Top Gear magazine and is scheduled to be completed by June 17, so we may learn what this maniacal mower's true purpose is then.
According to TG's report on how the build is going, as well as the video of it being fired up (literally) for the first time below, there aren't many actual mower parts left on this machine. What started out as a Honda HF2620 mower now sports wheels and tires from a racing quad, a back axle from a go-kart, a steering rack from a Morris Minor and a 1000cc engine from a Honda VTR1000F sport bike. All that remains from the original mower are the pedals and body panels; even the steel cutting deck has been replaced with a lighter fiberglass version. And blades? This mower will be bladeless, instead using two electric motors to spin lengths of brake cable like a weed whacker.
