DMC,
You remind me of something that happened in Washington a few years ago. Blonde, vivacious Mom leaves twin 4 year old boys in the Land Rover Discovery, running to boot, while she run inside a convenience store to get a pack of cigarettes.
Boys unbuckle themselves, put the thing in reverse somehow and it ends up parked ontop of a bus-stop bench. Thankfully no-one was killed.
I saw that on the news one night. Really humbling thought...maybe street racers aren't the problem; it's the everyday average Joe that's the problem...
