Driverless cars having fewer accidents is a bold (i.e. false) claim.
We already have cars that are shared and go exactly where you want to go: they're called "taxis".
Any price reductions (and environmental benefits) arising from electric vehicles are achievable with existing vehicles - and drivers.
Any cost savings achieved by sacking drivers will go to profits, rather than being passed on in price reductions: that's how capitalism works. (Have you noticed supermarket prices coming down as a result of self-service tills? Me neither.)
Bus drivers don't just drive: they provide hugely important services to passengers (information, safety, accessibility), but I wouldn't expect someone who was born the heir of an Apartheid-era emerald mine to understand the first thing about public transport.
