Bingo, standard feature AND known to perps. Unless you offer a free retrofit for alarm and locked back seat for all Teslas, it will not be standard as far as perps are concerned. In order for perps to know that for example the rear seat will be locked, they need to break into a bunch of those cars to learn it (they don't read TMC
). The problem will be, once they learn the seats don't go down, they'll learn to smash the read hatch window and get in through the shelf. So now you'll need to add a lockable and hardened rear shelf. Back to the problem of perps knowing - even if 50% of cars are locked and secured, thieves will still keep on trying if their experience tells them 50% of the time there is no lock or the owner just didn't lock it.
Bottom line is, for the thief it's always a risk vs. reward calculation, even if they do it intuitively rather than mathematically. The higher the risk:reward ratio, the less likely for the crime to happen. If you lower the risk by decriminalizing the activity, you'll need to lower the reward by the same amount. Lockable/secured storage reduces the reward, but if it's only on some cars and only some owners use it (lock it) then the reward reduction is only partial. An alarm doesn't decrease the reward, it increases the risk but only ever so slightly if the consequences of getting caught are small. So say 10% higher chance of getting caught and having to pay $100 fine, so if you change of getting caught was 10% to start, the alarm adds a $1 expected cost per break-in (10% original chance of getting caught x 10% due to alarm x $100 fine).
