the incident I referred to... I just happened to be following a Florida Highway Patrol officer as we approached an intersection with a rail road crossing, and encountered a momentarily puzzling scene... what in fact I was looking at was a Chevy Tahoe SUV wedged at 90degrees under the bed of a semi, front window smashed and pushed to the steering column ...rear wheels still spinning, and billowing blue smoke...both front doors were inoperable and the FHP officer then attempted to break the rear passenger door window, requiring more than a half dozen hits with a PR24 baton... at that point the rear tire ignited as he entered the SUV to take it out of gear...I emptied my 2 1/2# bottle just as fire rescue arrived, and they quickly got a hose reel into action as the tire was still smouldering... ... I didn't really want to take a look at the driver...
