Here is your mission, should you choose to accept it:

Design a portable EMP gun I can use to zap and disable stupid drivers' cars.

Some people should not be allowed to touch a set of car keys. I think it's time we get proactive with them.

I told my wife I'd like to make one, she wants one to carry in her purse. I want one mounted in my front yard that is "Subwoofer" Activated! I'm with you as the cops don't do anything about it. Maybe we should get laws passed that prohibit "Subwoofers" from being installed in an automobile!

Don't you just tune them out after a while?

How about a really powerful shotgun for silencing car alarms in the middle of the night?

Yeah, the subs seem to drive away; those damn alarms are stubborn

Or one could always move to a better neighborhood
