Well I think one can start with a bit of an average car. I mean humans vary a lot too. Both in size and resilience. If there’d be some wireframe made that can represent a bit of the car rigidity of an average 2008 car for example we can definitely see how this monolith would vaporize any car, versus the Jazz that’d mostly dent itself in a crash. And include that in the rating as well.
Current SUV trends are abysmal for others with their 800bhp and near 3000kg kerb weight. It’s I think a solid way to stop this race to the bottom.
