Good point! Lots of folks don't seem to concern themselves with safety equipment until they've had to rely on it a time or two---then it seems to go up on the priority list!!! As for the guy/car in the video---what can you say other then obviously a very poorly thought out and built car, suppose the rest of it was put together with the same incompetence as the seat and belts????
Another lesson I learned the hard way, even on the track the other guy's mistakes can take you out....Scary to think that without some good tech people at the track that a car just like that '55 in the video might be in the other lane!!!!
The way he was hopping down the track and the way that car handled ,I guess I would have to say that I don't believe that too much thought went into the car in general.
I am trying to make my point as kindly as possible.
