They are using a Prius v as a test vehicle... MIT built a self-driving car that can navigate unmapped country roads - The Verge
it wouldn't be surprising if someone came up with a better system that negated the billions spent on current tech and the rR&d that preceded it.
Development has to start with a safety culture, or lack thereof. Tesla engineers wanted more sensors on cars
Oh those wacky lads at MIT, just another way to seek out that last cold beer at the tavern located down that lonely country road on a dark and stormy night!
So? I thought that the original DARPA autonomous vehicle challenges, predating the modern self-driving car movement, included unmapped roads and even off-road segments. DARPA Grand Challenge - Wikipedia
Judging from the steering wheel displacement, the MIT car does seem to be weaving back and forth quite a bit as it goes down that country road!
I remember watching the 2005 & 2007 challenges on I think the Discovery channel. It was very interesting.
