But someday I'd really like to see an open source version of a road capsule.
Mainly aimed taking existing cars and running them like trains on a track.
1) Stop when an obstacle is in front 2) Automatic follow the current lane, maintain a safe distance with car in-front and follow the speed limit. 3) Parse traffic lights and be able to make turns. 4) Wait for passenger to get in and out.
There's no reason why I can't take a short nap while I'm on a 100km straight road going cross country at night when there are almost no cars on the road.
I'm betting that someday in the future we're going to have lanes on road specifically for self driving buses/cars just like we have dedicated train lanes.
Lidars can be more effective than stereo cameras (although they have tradeoffs vs. stereo in some use cases).
