Except when they drive home after parking in a normal parking lot with no electric.
So at about 6pm it will be 22 F and dark here today ,and its the warm day of the week here Thursdays and Friday's high will be ~ 16F,
Even worse maybe in the summer sitting at those traffic lights or traffic at ~ 100F with that sun beating on the car and into the coach thru the windows.
Teslas are for wealthy people to park in their garage : )
