It depends on how much of a wash you are doing and how long it will take, I think you should provide several choices of wash and charge according to the wash needed. I clean cars and sometimes one car takes a whole day (Inside and out)

One way car rental is certainly possible, although there may be a one-way charge involved. The exact charge depends on the rental location, car size, rental duration etc.

Every single car in the world only has one motor so yes it is possible.
You are at fault - The charge where I one worked was, "Backing Without Caution."
The Sodium atom with be positively charged [it will have a single positive charge]
