When I was in highschool, WAAAAAAAY back in the mid 90's, my buddy was driving and (OLD) Subaru Bratt. He's driving down the mountain to early morning baseball practice and the thing starts shuddering. He figured it was another tire with a bubble in it (which by the way, *I* had to find the jack and spare, on top of the motor), but then he saw the thing wizz past him down the fairly steep grade. It was a long walk to the auto parts store for him for some new lugs...
