Google’s new self-driving car: Electric, no steering wheel

You are looking at Google’s very own, built-from-scratch-in-Detroit self-driving car. The battery-powered electric vehicle has as a stop-go button, but no steering wheel or pedals. The plan is to build around 200 of the mostly-plastic cars over the next year, with road testing probably restricted to California for the next year or two. . Google’s new self-driving car is incredibly cutesy, closely resembling a Little Tikes plastic car — there’s even the same damn smiley face on the front. The cutesy appearance is undoubtedly a clever move to reduce apprehension towards the safety or long-term effects of autonomous vehicles — “Aw, how can something so cute be dangerous?”

Disappointingly, Google’s new car still has a ton of expensive hardware — radar, lidar, 360-degree cameras — sitting on a tripod on the roof. This is to ensure good sightlines around the vehicle, but it’s a shame that Google hasn’t yet worked out how to build the hardware into the car itself, like other car makers that are toying with self-driving-like functionality. (Or maybe it has, but doesn’t want to invest additional money and engineering time until it’s time to commercialize the car.) In the concept art below, you can see that the eventual goal might be to build the computer vision and ranging hardware into a slightly less ugly rooftop beacon

These first prototypes are mostly of plastic construction, with battery/electric propulsion limited to a max speed of 25 mph (40 kph). Instead of an engine or “frunk,” there’s a foam bulkhead at the front of the car to protect the passengers. Internally, there’s just a couple of seats, and some great big windows so you can enjoy the views (which must surely be one of the best perks of riding in a self-driving car).

Removing everything except for a stop-go button might sound like a good idea, but it’s naive. How do you move the car a few feet, so someone can get out, or for backing up to a trailer? Will Google’s software allow for temporary double parking, or off-road for a concert or party? Can you choose which parking spot the car will use, to leave the better/closer parking spots for your doddery grandfather? How will these cars handle the very “human” problems of giving way for other cars and pedestrians? Can you program the car to give way to a hot girl, but not an angry-looking trucker?

Google is now safety testing some early units, and will hopefully scale up production to around 200 cars that could be on the road “within the year.”
