Re: Huge study about safety can be misinterpreted by SUV drivers
This is just ridiculous... comparing apples & oranges isn't helpful.
The advantage in a large vehicle is in vehicle to vehicle collisions; there is no advantage in single-vehicle accidents (i.e., rollovers). The large vehicle ALWAYS enjoys the advantage in any collision with a smaller vehicle. Attempts to deny that simple fact based on the laws of Physics using all kinds of clever statistical manipulations are simply absurd. Different vehicles enjoy advantages in different types of accidents based on their characteristics; wide-brush prejudicial generalizations don't help rational folk in the task of making informed decisions. This, and messages like it, are just political propaganda... plain & simple. Rollover: advantage: low center of gravity REASON: increases leverage required to roll (lever angle) winner: lower - heavier makes it better loser: higher - lighter makes it worse advantage: wide wheelbase REASON: increases leverage required to roll (lever length) winner: lower - heavier makes it better loser: narrow - lighter makes it worse Collision: advantage: high MASS REASON: more mass reduces accelerational forces after collision winner: heavier - good crash test performance makes it better loser: lighter - poor crash test performance makes it worse Spinout: advantage: long wheelbase REASON: increases leverage required to spin winner: long - heavier makes it better loser: short - lighter makes it worse Mixing the statistics for these VERY different types of accidents is poor statistics at best... and deceitful or even outright dishonest at worst. But these are the political times we live in... The comment about limiting size for everyone is socialist at best, communist at worst... and very authoritarian for sure! There's no reason that large vehicles can't be A LOT more economical... why not concentrate on that? The comment about limiting speeds for trucks, etc., is just absurd. Can you imagine the outcry from the truckers? We can't even get them to obey the speed limits now! Not to mention that while the standards for my vehicle's exhaust have become draconian, nothing at all has been done about truck and bus exhaust. Nor are there any CAFE standards for their fuel efficiency. If this was a real effort to increase safety & ecological concerns then TRUCKS & BUSES are the place to start! And, just to top it all off, do you really think you're safer hitting a large truck with your tiny car just because you made the truck drive slower? If so, THEN YOU DON'T UNDERSTAND THE PHYSICS AT ALL!

Re: Huge study about safety can be misinterpreted by SUV drivers
You are an idiot bud.
If everyone drove heavier vehicles, fatalities would go down just as the numbers below indicate. I do note you don't show any numbers for little econo boxes. Why, are they something like 10 fatalities?
