When in a built area I always lock all the doors and boot.
I've had work mates who put there lap tops in the boot of their car, then when they stop at traffic lights, or similar, someone walks behind the car and opens the boot. By the time you realise what is going on your lap top, bag etc etc has gone and the traffic lights are green and the traffic starts to move. What do you, leave your car running and chase the thief while the traffic tries to move away or move with the traffic and let the thief go
