Charging points can vary speed wise depending on make and model. As Alan said certain types of houses will have serious problems as most terraces don't have off road parking so charging points will be problematic. Also in very cold weather some batteries like their charge very quickly. Availability of charging points in public areas are still very hit and miss depending on region and are particularly poor in rural areas.My brother in law has a tesla but he never travels far so hasn't had any problems, he was looking at a trip to the Highlands but decided against it as he didn't know what access to charging points would be like. The batteries are moving forward but some electric drivers are still reticent of certain journeys because of the ease of petrol/diesel journeys.
