Not in Germany, but I do have a dedicated parking space, I could totally afford an electric car, an yet it would not be practical to get one. Here are my reasons:
- I need one car, not many (I'm lucky to get _one_ space, ain't gonna get several!).
- I can't charge it there, there's no infrastructure. Sure, I can ask city to add infrastructure but... good luck with that, it's going to take a while, there are a lot of problems to solve (besides actually installing power near my space, we need a meter to charge me, and it needs to be a "smart meter" that doesn't allow everybody to use power paid by me; it needs to be at least moderately vandalism-proof. And I need to find a way to leave my car plugged in for extended periods of time, unsupervised, without fearing that someone will steal stuff from it - e.g. the charging cable?)
- If all the above are solved - I still need to use that car for extended trips (vacations, visiting parents in a different city). Those would still mean that I need to charge "on the road". Due to the first point, it'd still be a challenge to go 100% electric even if I had the "charging at home" part covered.
Really, I think if we don't solve the "charging in gas stations" part, electric vehicle use is going to be inherently limited.
