Never leave more than the ignition key with a parking attendant. If someone has a weapon and demands your vehicle, don't try to resist. Give it up and run to safety. Then contact the police as soon as you can. Never keep a spare magnetic key under your car.
Experienced thieves know where to look.
Avoiding Dangerous Encounters Try to avoid altercations with other motorists. Even if you've been cut off, tailgated or otherwise wronged on the road, risking a fight is simply not worth it. Get a cellular phone and keep it charged, ready and easily accessible in case of emergency. Be careful when using your car horn. Honking often leads to angry encounters between drivers.
