Convert public fleets. It's much more reasonable to mandate that local councils and public servant staff cars should be EV-only first; these tend to have short turnover periods of three to five years anyway. That forces the public bodies to actually address the details of adoption.
Not to mention buses and public works vehicles like refuse lorries. Expensive, but if the transition has to happen it has to happen.
But I think the momentum is there on its own:
> In August alone, 154,582 EVs were snapped up, accounting for 20% of all new car sales. Analysts note that a 20–25% share is enough to meet the EU’s emissions targets for 2025–2027 and Europe has just reached that milestone.
There's a self-reinforcing circle that as more people have EVs, they become more "normal", and the more car-centric policy caters to their needs. People who are irrationally scared speak to friends who own one or ride in EV taxis (actually, taxis are nearly always hybrids at the moment?)
I don't think that is rational at all. Have you ever looked at vintage car regulations in Europe? There are none, basically-- if your car is old enough, neither accident nor emission mitigation/prevention are required at all.
Why would you expect that this is going to change?
