Tesla S has a range of 400 km. This makes the cost 5.31 € per 100 km. An average ICE car of the same size uses, let's say, 8 L per 100 km. The cost for the ICE is then 11.2 €. Twice as much. Don't forget that: you can charge at free stations, charge at a free supercharger, and you can charge the car at night when the electricity price is lower( 25ct is quite high btw ), while the price for the petrol is always the same.

Only if you have a garage. Plenty of people park on the street overnight, which is a non-trivial problem.
