I had a customer's S2000 we prepared for SCCA T-3 competition. I maintained the car and he was always spending $$$ on the latest and greatest stuff. One day he drops off a RaceTech "halo" seat for me to install. After one look at it, I told him that I would not install the seat and that if he wanted to upgrade the seat, consider something else without the helmet halo. He argued a bit and I told him that I would put it in the car if he would stop back at the shop with his drivers suit , helmet and Hans. I needed to prove a point, so I tore out his old seat and simply set the new one in its place. When he arrived and suited up, he was able to climb in the car over the top door bar, but barely. He had a cocky reply and said, "see, no problem". "Yep" I replied and proceeded to shut the door and told him that he just crashed and needed to get out the window opening since the door wouldn't open. He looked at me perplexed and said that it wasn't going to happen. I then said that the car is on fire and you have seconds to get out the passengers side. Well, between the belts, comm cables, right side net, halo seat, shifter and everything thing else, after a few seconds he removed his helmet. I said, "you just burned in the car, I'll call your wife". He didn't think about all of the consequences and even though the seat was safer, to what end?
I explained to him that it wasn't my first rodeo. I had a car fire after a blown motor at NHIS back in the early 90's and my brother almost burned to death in his car at Pocono. You race long enough and you'll have incidents, not necessarily accidents. I'm here typing this only because of training beyond driving. In my incident at New Hampshire, I pulled off in the grass after the blown motor. Besides the oil smoke, when I pulled onto the grass, the hot rotary exhaust didn't help matters and there was a fire under the car. I ended up out of the car quickly but when back in the pits, my father asked why I didn't open the door of the car to get out. I said I did, but after looking at video that my mother was taking, I actually climbed out the window! Out was out regardless of the path to get there, but it happened quickly because I practiced on how to do it.
With all of the cables attached to a driver nowadays, cool suit plumbing hoses, HANS device, belts with sternum straps, window nets, right side nets, sometimes a second window net(yes 2 of them), all of the gauge wiring in the car, fire suppression system plumbing, Accusump plumbing, petty bar placement and general rollcage layout, you better know how to quickly and efficiently remove yourself from the drivers seat. Your life might just depend on it! Please read this and take it to heart.
