It’s something like 7-8 miles on European grid (for Model S), I.e. still not enough.

What is fine is if you stay in a hotel for one day or more.

My Model 3 adds 17km/h at 220V (EU). => 200 km range if you arrive at 6pm and leave at 8am. THis is not a full charge, but it is more than enough for my daily routine.

But I understand, there might be some use cases where this is not enough.
