I don’t have an electric car but my parents have an electric non-Tesla one, and say that firstly you have to sign up to accounts with loads of different companies just to use them, and then secondly it’s really common to arrive at one and it just doesn’t work or there is only a few and charge points which are full.

Teslas currently have the advantage of the extra supercharge network, although in the Uk that is being opened to other electric cars which will level the playing field.
