(I'm assuming petrol stations are private enterprises in Germany on this point)
Privately run charging stations on public sidewalks are few and pricey and most of the time sitting empty.
So it's clear that if you want a mass switch to EVs the government will need to subsidize the infrastructure to make EV charging affordable. However, digging up the sidewalks of a whole city with public funds to cable it for EV charging is the last thing taxpayers want to hear even in green Austria since it's seen as a something that will only benefit the top % that can afford EVs and they already have charging stations at their houses.
So we're back to square one.
That's still 20 minutes longer than it should take. And probably around 15 minutes longer than it takes to fill up with gas (which will give you twice the range). Speeding that up makes sense.
(To be clear, I don't think it's reasonable to mandate swappable batteries, for instance; there's far too much innovation and potential innovation in battery technology for that. However, I think it's reasonable to experiment with that, and any other solution that will let it take less time to charge.)
If people are willing to pay for this service, someone will be eager to make a buck and supply.
There is more money to be made in not providing the service and slowing down EV adoption, environment be damned. That makes it the perfect situation for the government to jump in and re-align those incentives.
(Including eg just drive your existing cars less. 50% reduction in driving existing cars is as good or better for the environment than eg 50% conversion to electric cars. But I don't expect the government to know what is better for the customer.)
