[QUOTE=the_ulf; i don't actually see a problem with changing a wheel by the roadside. i did it before RFTs became a thing without incurring loss of limb or life.[/QUOTE]

I don't have a problem with changing a flat on the side of the road either. But my wife takes the car sometimes and I would rather she just drove home or to safety. In my area most of the travel is on superhighways so moving along with traffic is important and getting off an off ramp at night in some neighborhoods has its own risk. I would easily sacrifice a tire, a rim, or a major repair to get her home safely.
