There is a massively more inconvenience (cost aside again) in having your phone stolen versus your car. It could upend your life a lot worse than having your wallet or laptop stolen as well.
There are only so much things we can expect from the average consumer and theft of a phone massively changes that persons life.
I’m for increasing the resources put into specifically phone theft.
My laptop was stolen from the airport (inside security!) and I had needle like precision with where the cops could find it. Nothing was done and I simply got back the insured value for it and the items with it. It put me out of work for the trip I was taking but I’m not your average consumer and everything was backed up and I did still have my phone. If my phone had been taken and not on me I would have been in a much larger world of pain (though I have backup codes, etc.).
