No, the regulations are not too strict fir small cars, that us what the car industry wants you to think. The regulations for obese cars are far too weak and there is zero enforcement against ommercially used car categories being sold for pure end consumer use.

That is by design due to a breakdown of proper functioning of institution and massive degradation of regulations by negkect and legalisation of massive loophole exploitation, even widening those loopholes instead of closing them.
