Weight-based Collision Fine

In collisions between cars (let's constrain this to 2-car collisions for simplicity), the heavier vehicle imparts more damage to the lighter vehicle (and its occupants) than the lighter vehicle does to the heavy one. This is obvious. And the greater the difference in weight, the greater the disparity in damage to the vehicles and people. I often hear SUV owners justify the big size of their vehicle by saying that they have greater (perceived) safety. However, this safety (whether or not it's real or perceived) comes at the expense of the safety of the person in the lighter car. To a degree, this is effectively saying "I care about the safety of me and mine, all others be damned." Whereas the owners of the small cars have effectively become a net "damage/injury-sink", imparting less damage than they receive.

My proposal is to scale the fines given to heavier vehicles at fault, based on the ratio of vehicle weights involved in the collision. If a 7688 lb Excursion collides with a 2387 lb Miata, and if the Excursion is fined, the fine should be increased by a factor of 7688/2387 = 3.2. (However, I am not advocating reducing the Miata's fine by 3.2, if it were at fault). If two Excursions are involved, then nothing is increased, since 7688/7688 = 1.

This might seem to be an Anti-SUV rant, and to a degree, well, it is. But I'm not targeting SUV's in particular. A Lincoln Town Car that weighs aprrox. the same as a Dodge Durango (300 lb. difference) would be penalized without prejudice if involved in a collision with a Mini Cooper, and by the same token, the aforementioned Excursion would be penalized for hitting either the Dodge Durango or the Town Car.

Note: I'm not proposing creating any new class of fines or penalties. If a jurisdiction deems the fine for a low-speed rear-end collision is $150, so be it. I just want that fine scaled by the ratio of the vehicle weights if the heavier car did the hitting.

Also note: Devil in the details - do we use GVW (Gross Vehicle Weight, the max weight the car can carry), Curb weight (the weight of the car sitting in your driveway with fluids, no people), an average of the two, ... ? Doesn't make too much difference. I don't suggest actually weighing the vehicle, or weighing all the occupants to get an exact weight. It's the effect I'm going after here, so going with curb weights is probably fine - they're printed on the label inside the driver-side door frame, so it's easy to write the ticket with those numbers.

Final note: Go easy on me. This is my first idea! =)
