Confirming #2: I live in Switzerland (low crime rate etc...) but I would not even dream of leaving my phone visible in the car.
Btw. in the 90' I used to detach each-single-time that I parked the car the front panel of the car's radio to then carry it with me (leaving the storage box in front of the passenger seat open, to show that I didn't just put it in there) to discourage people from breaking into the car to extract the radio (front panel & main car radio were individually coded to only work together, that's at least what I believed).
What a silly thing to do, hehe, but to be fair the price of a fancy radio at that time was similar to today's phones ("Pioneer" and "Sony" were high on my list - some models had quite complex display animations/colors/equalizers/etc & sound modes).
