As for driverless taxis and the like, again a huge hurdle to get people to trust them.
Freight will be the first casualty, for reasons already stated.
As for passenger trust... we are not talking about this happening tomorrow, we are talking maybe 30 years.
30 years ago people didn't trust "jap junk" cars.
30 years ago people had only just started to understand and trust desktop computers.
30 years from today do you think that people still won't trust an automated passenger transport vehicle?
We can stick our head in the sand and "cross that bridge if we come to it".
Or we can start thinking about ways in which to prevent this probable (or even just "potential" if you prefer) unsustainable socio-economic situation.
First car I owned was a 1978 Toyota Corona a brilliant car , you need to go back 40-50 years
Computers, again go back 40 + years, CPM, Apple II, TRS-80 , Xenix
I would expect rail to come first, its a more controlled situation.
