I just about had to grab Mum and haul her out of the way in a parking lot an hour ago. A woman with rear wheel drive didn' know enough to drive around the piled up snow drift (a bus had just done it) and then tried to get through it my gunning the engine. Of course, she slewed the arse end out and came close to pinning Mum and I to another vehicle.

As said above, knowledge is paramount.
