The actual roadblock (sic) to e-cars in Europe and especially Germany is that culturally, people don't live in the urban sprawl (one house one garage per family) but more like Americans do in big cities like NYC: Multi-flat apartments with no reserved parking spots - street parking is the norm, and in bigger cities is very hard to find in the evening. That of course means overnight charging is only possible for those who own a parking space closed off to the public, and can convince the person who they rent from to install a charger. Then you have the further problem of the electric grid in most cities not being able to supply the needed bandwidth for a big number of fast chargers. That'd mean that the whole grid would have to be upgraded, so digging up city streets for the next decades. People in the sticks who own property (single house on a plot of land) are those who can reasonably switch to electric cars for the time being, because let's face it, no amount of chargers at service stations will be enough - if I can't charge my car overnight at home, I won't buy an e-car. I'm not driving to the next service station, wait for a charger to become available, then sit in my car playing Vampire Survivors for 2h until it's charged. Every other day.

I seriously doubt electric cars will take off in Europe due to the lack of the "charging at home" option for the majority of people with no real resolution in sight.
