traffic congestion can be fixed in our lifetime
Googles self-driving cars are on the road right now.
Designate some "self-driving car only" lanes, charge an extra toll for access, and then self-driving "platoon driving" (with no rubber necking) will solve quite a bit of the congestion we have now. With the extra toll and the reduction in accidents, it will be a net win financially.
CA should lead the way with self-driving cars, instead of taxpayer boondoogles.
