Here in Germany regulations are unnecessarily complex and your best option is to get 10-20 year old Velomobiles that can legally be driven as S-Pedelecs (up to 45 km/h) because they were at some point certified for that speed.
But getting a new velomobile, that you can easily drive faster than 45 km/h by muscle power alone, certified to be powered electrically is apparently near impossible (i.e. not financially feasible).
Not even sure where I'd park it, maybe my building's small motorcycle parking lot has some space.
Definitely... The market is too small and everything is built by hand. You can get reasonable used ones for 4000-6000€, but you probably know that.
Otoh you save gasoline which pays for itself after a while (3 years in my case, not counting insurance or maintenance).
> it hardly has more space to bring stuff than a normal bike
It's a bit more and it's safe from the elements. Some 4-wheel models have an actual trunk.

Doesn't bother me either, riding bicycles in the rain is surprisingly ok.

Maybe try one out. I was convinced of the concept when I could easily keep up with my SO who was doing 45 km/h in a e-VM during a test ride.
That said: I don't own a VM either because it never made sense... Either my workplace was too close or too far for a VM to make sense. But I think there is a sweetspot of around 20-40km one way, where a VM is a great alternative to normal bikes and cars.
