Is there a thing as too much HP's?

[G.Irish]

I don't disagree but at the same time, F=MA. Up the acceleration and you don't need as much mass.

Not quite. F = ma in the case of a car refers to how much force is applied to accelerate a mass at a certain rate. When you are talking about a collision you need to calculate momentum. Momentum is mass * velocity (p = mv). So in a 60 mph collision, a 3500 lbs CTS-V would have to be traveling 94 mph to equal the momentum of a 5500 lbs lChevy Suburban. And if you're talking about Semi's its an even bigger disparity.

If you really want to make things safer in terms of collisions you would need to enact a momentum limit. Lighter vehicles could go faster, while heavier vehicles would need to go slower. That would be the only way to be fair.

I didn't think legislation was necessary to deal with some of my concerns with SUVÔÇØs because at such large production numbers, the market would be able to regulate itself.

However, I don't think that companies should be allowed to produce cars that are essentially PR/Marketing tools that are harmful to society and costly to taxpayers. In my mind, I see these cars as a marketing tool that externalized its costs to the taxpayer.

You'd have to talk about the exact externalities imposed by a given vehicle to be fair. An SUV or truck uses a lot more gas, emits more CO2, puts more wear on the road, takes up more space causing more traffic, and endangers other drivers more than the average sports car. On paper it seems like an ultra fast car is a public menace but in reality it is hardly a factor.
