I've had my car broken into twice in SF. Everyone's response to this is always "you can't leave valuable things in your car". Both times, my car was empty. Nothing was stolen. I have never left anything valuable in my car -- visible or hidden, trunk or otherwise. Not sure why people keep giving me this advice.

I always keep a roll of duct tape and some cardboard in the car now. I tape up my quarter glass (the smallest of the rear windows that thieves love to break) and cover it with cardboard, to make it look like its already been broken into. I also leave my back seat down w/ a clear view into the empty trunk. That's the only thing that works.
