I agree that cars are here to stay and are currently "nigh on essential" but I disagree that they are convenient (unless you close your eyes to the true costs) or that universal transport service is too expensive... but maybe we differ on how friendly "user-friendly" should be.
The current level of car use is not here to stay, though. It's completely out of control and proportion and unsustainable. Cory Doctorow has said "geometry hates cars" and he has a point: there simply isn't enough space in our historic towns, cities and villages for everyone to be dragging around a 4m x2m metal box and definitely not with 12m or more of headway. We shouldn't flatted more history to make space and EVs will not solve this. Making cars slightly smaller will not solve this, not until they become smaller than 2m x1m and use a bit of human power and a 15-20mph top speed to reduce the size of the heavy battery being carried around... and hey presto, we've reinvented e-bikes.
So then we need something for longer and faster journeys, which will be mass transport, trains and medium/long-distance buses, so I disagree about where public transport is needed most: it's to span the sparsely-populated gaps more than move people around densely-populated areas. People can walk and bike most smaller densely-populated areas.
Yep, EVs are losing the plot because they're being sold as glamour goods, not transport. The main thing EVs do is remove the "cost of fuel" discouragement of/limit on car use for those rich enough to afford an EV.
Has anywhere ever legislated to do that?
