hmmm pushing into location - embarrassing . unless not allowed to drive it for some reason ?
that is normal for TV commercials that film several takes of the same scene over and over again.
for something like this, it is easier to push it "back to one" to restart the scene rather than have the driver back up.
It is also possible that the car does not run and they simply give it a push to get it started and let it coast. Someone posted a clip of the advert off TV and it does not appear to move much in each shot.
The grunt work of moving it around is performed by P.A.s (Production Assistants), that is what they are there for.
