I live in NYC too and despite being in a relatively safe and pleasant area, I still cringe watching a driver try and parallel park his/her car. This is not to mention any acts of vandalism or the inevitable bump and tap by a less-skilled driver.
At least with an expensive watch, I can slide my shirt cuff over the timepiece and shield it from any unwanted dings/looks/careless people.
Besides, the public transit system is superb so no real need for a car. If I am in an unsafe situation, I can simply hail a cab. No need to worry about car-jacking or finding a spot later on. Garages are a viable option but I get paranoid that the parking attendant(s) will having a Ferris Bueller joy-ride with my car.
