you're right about sharing, but its a couragous policy to sell to the public cutting 30% off from ownership, especially given the demographics it would effect. on other hand, the urban terrace dwellers have most access to public transport. also those high power chargers will need most domestic supplies to be upgraded, probably local substations and cabling to support too.
It needs to be applicable to everyone or it doesn't work, you are correct. The courageous move would be to do it now, before EVs are ubiquitous in the UK. Self drive technology would help, so your car comes to you when you need it.
The grid capacity questions still remain, but if every town had a large vehicle hub, with 1000s of EVs on-site, you've got yourself a large semi-permanent Vehicle to Grid battery right there, which can be used to even out grid demand, taking excess or providing power as and when needed.
