You do realise then when you're a police officer and your friends are getting raided you can't just quit from your job and go help them within the raid. You're basically saying that you're too lazy to go to the Parking garage (a two minute walk) to get your car and want it to magically stay there.
In real life, your car does not disappear when it's not parked correctly; you get a ticket and it gets impounded if that ticket is not paid - Exactly how it is in the game, your car shouldn't just disappear; to be honest it's quite annoying that it vanishes after a certain amount of outstanding ticket time however there does not seem to be much work-around for this.
This is completley not needed, it would not benefit anyone highly and joining a job is basically starting a new life therefore seeing your friends in a raid, getting information from the police radio and then going to glass co is practically metagaming.
Dumb.
