Yes, that's a very good point. Imagine if every house in the street
was charging its electric car(s) overnight -- it's pretty unlikely
that the local sub-station and wiring could handle the load. It may
be OK if just one or two houses use 13amp sockets, but not if the
whole street is doing it for hours on end.

Also I wonder how many house fires they might end up causing if a few
hundred amps is put through ancient wiring for 12 hours without a
break.

I think the car needs no more than 13 amps from a 240v domestic supply
for eight hours for a full charge, or can be charged very much more
quickly using a 400v 3-phase supply (not available in many houses, of
course). So individual houses may be OK charging one electric car, but
the neighbourhood supply may run out of juice if they're all doing it at
once.
