I have intimate knowledge of the grassroots levels of the sport, and must disagree.
There are still teams so tight on budget they choose their track¹ based on it not requiring fireproof gloves as part of safety equipment, etc.
I have heard similar stories about needing to avoid tracks with safety rules due to unaffordable expense of:
- Safer bladder style fuel tanks
- Head-and-neck restraints (to avoid having your head detach from your spine like Dale Sr.)
- Fuel line and engine fire-wall sizing
- Helmet and firesuit regulatory tag-checks (every additional second in a bad fire matters, old aren't safe, sometimes in more ways than one).
¹Or don't race at all, anymore.
