Google told Automotive News Europe sister publication Automotive News that its self-driving Lexus was not at fault in any of the crashes, but would not release details.
The company’s new prototype uses the same software as the RX 450h, Google said in a statement Friday. But the Google prototype is built for autonomous driving, and the RX 450h is a vehicle to which sensors have been added, a Google spokeswoman said.
Google’s podlike vehicle looks like something out of a Disney Pixar movie, with black domes on the roof and hood that hide the sensors the car uses to navigate roadways with the help of maps and software algorithms.
Google says its prototype is limited to a top speed of 25 mph (40kph), and during this testing phase Google drivers will ride in the vehicle with a detachable steering wheel, accelerator pedal and brake pedal to allow them to take over if necessary.
