Interesting take on if you should use the locks on your car.
My take on the lock issue:
1. If I'm driving, I would have to stop to get in the boot. Why not have the same key as the ignition.
2. If I need to get in the glove box while I'm driving, I don't lock it. If it's locked, I'll pull over. What is so import in there that I need to keep driving?
3. I do lock my doors and trunk. To keep someone from simply opening them up and getting into my car. I don't leave anything inside the car to tempt someone from seeing and wanting it. The only person who is going to cut the top or break the window to get in, either wants what they see inside or wants to steal the car. The person who wants to steal the car, may pass because the doors are locked. Any one who really wants it or a professional will take the car no matter what we do. Lock the car, top up and windows up.
4. Lock the trunk. Always.
The kill switch is in there. That should stop the car thief who tries to hot wire the car and does not know about the kill switch. (Again, if the thief is a professional or a knowledgeable Healy guy, nothing will stop them).
5. Parking attendants: Yup, they will have access to my glove box and boot. Not that I would ever let one behind the wheel of my car. I'll park it, thank you very much.
Yes, don't leave valuable showing in your car. That's probably more of a risk than having the car stolen.
IMHO, it's better to lock a car than not. I think it deters trouble.
