Charging. The network of chargers and the billing is a shit show. Also service which is somewhat variable.
If I fast charge anywhere reliable here (instavolt) in the UK I’m better off driving a petrol car. Helm a coal powered one is probably cheaper. So that limits me to home charging which I can’t do any more because I live in an apartment block.
Owned a model S and have rented a Polestar numerous times.
