I second StinkyPete, the best way to prevent theft is to not leave things in plain sight. If you leave your phone or wallet on the seat while you're visiting the doctor, that's an invitation. I would also speculate that most thefts take place at night, when most sane people are asleep or stealing from cars, thus by the time someone looks out the window... it's a little too late; the thief is probably around the corner already.

Other than that, no sane thief would bother stealing a Zoe even for spare parts (market is too small); these guys are focused on stuff that they can get rid of in a day or two.

I doubt EVs need immobilizers; since the entire power train is controlled by software, there's very little mechanical stuff involved (there are no hot-wires); you need a keycard to activate the on/off button so the simplest way to steal an EV is to steal the keycard or duplicate the key codes.
