“It's a truck full of traffic lights”
I am fairly confident that the autonomous car business model is pretty dead.  Electric cars - that's great ! But self driving is waaaay harder.  And self driving has a inbuilt expectation of nearly perfect.  It's not that if we swapped to self driving cars today we would halve car deaths (which would be something like 500k people pa - which would be a huge very important thing) but it would not be perceived as robots save 500k people a year, it would be instead "robots kill the other 500k per year"Liability, insurance, legal minefields and plain old marketing would never allow cars ,that perform as well as the best performing cars do today, to be on the roads in "every day" conditions.My conjecture is we end up building AV only roads. initially one lane of a highway, then ring roads round cities and major warehousing hubs, then across urban areas.  Walled off in some way they simply become railways with benefits.At that point every business model ever written with Self Driving in the title goes in the bin.I am not saying the tech is useless - frankly it's fucking awesome that this is happening in my lifetime.  But fucking awesome tech and workable business model aren't always the same thing.Not sure where I am going with the rant but I sure hope we get more out of the billions spent here than Teflon.
