Slightly off-topic and maybe against the typical viewpoint of the site, but if they spent this much money on bike lanes, e-bikes and public transport, self driving cars (and all cars) would get much better.
There isn’t a single day that goes by when I’m passing through a station in San Francisco anymore that I don’t see someone (and usually multiple someones) hopping the gates into BART and several times a week I’ll see one of the fare gates to MUNI has been forced open and is out of service. MUNI and BART could probably stave off some of the losses if they just put actual police there to ticket and/or arrest fare evaders, at least when it’s busiest.
At least in New York it’s politically touchy to discuss penalising fare skippers. (Granted, our police are municipal while the subway is state.)
My hope is AVs will reduce car ownership, which in turn reduces the amount of curbside space for required cars (Hopefully AVs can be parked at a few centralised parking lots). In turn this will allow for more bike lanes and bus lanes leading to improved active transport and public transport options.
