Maybe it is not the right solution but the problem is definetly there.

Talking from my own experience, last time I was on a vacation in Italy, I rented a fully electric car and sometimes I just charged it so I had free parking in the historic centers. Although there it isn’t such a big problem because in southern Italy there’s not a lot of electric cars but still I can imagine someone doing the same in busy places.

If this makes people charge only till 80% then they will go to charging stations more often, this means more side time of connecting to charger, starting it, etc.
