Not sure - just know that there were a spate of car thefts [from driveways] in my community because people left their cars unattended. After the law - none in my area ...
FYI:
Just the other day, I pulled into 7-11, got out and locked my car [like I always do]. A car pulled in right next to me. Driver got out, apparently left the car running. While I was getting coffee, I looked out the window to see 3 "upstanding citizens" climb in the idiot's car and drive off while he was paying for his purchases. 'Course, he tried to run and catch them ...
So may be driving to work in a cold car just to trade having cars stolen from the driveway at home for having them stolen in parking lots at work or the store?
So in your opinion the law is good because stupid people don't get their cars stolen? Since when is that a legit reason for any law - stupid or not.
