Really intrigued where your bias comes from because that whole post is a load of crap, particularly about motorsports. Firstly both seat belts and ABS brakes had nothing to do with motorsport. I didn't bother looking up the rest. Secondly, why would innovation in safety science stop just because they use a different fuel source? If anything, different car configurations would allow for new advances in safety. Then for the manufacturers of niche vehicles - they'll go exactly the same way as other companies that don't innovate if they don't innovate.
