| Well, they should.
The issue of stopping distance is debatable. Motorcycles are much lighter than cars, but also have a significantly smaller contact patch, which is exacerbated by the fact that since they are so much shorter than cars, under heavy braking, the rear brake is completely useless - ALL of a road motorcycle's braking power is in the front brake. This is why you see modern sportbikes with massive dual-rotor six-piston disk brakes up front, and a single pathetic two-piston platter on the rear. Also, handling a motorcycle under heavy braking is an art; not many people can do it well.
So with skilled operators, we'll assume that braking distances are equal.
Still, I am a far safer motorist at 55 MPH on a motorcycle than in a car going 35. Why? Because in the car, I'm insulated, separated from the environment. My mind can wander, I can have music playing, whatever. A motorcycle demands my attention, and is not very forgiving of flights of fancy. So I am less likely to get in an accident in the first place on a motorcycle, which makes it inherently safer.
Secondly, I'm less likely to hurt anybody besides myself on a motorcycle, assuming I'm not carrying a passenger. If I t-bone a car with my mom and brothers in it, the car's going to shake a bit, while I go over the handlebars and on to certain death, or at least certain months of physical therapy.
All in all, considering that motorcyclists are less likely to get in accidents (the smart ones, anyway) and that we implicitly take responsibility for such accidents by riding a motorcycling in the first place, I think speed limits should be 10 to 15 miles per hour higher for motorcyclists.
Holy cow. I seem to have illicited some responses when I wasn't looking. My argument is based not on statistics: it's obvious to me that going faster is more dangerous. What I'm saying is, in a perfect world (without weird health insurance or $20,000 funerals (!) or responsibility to family or any of the other the things that mean other people are hurt when you die) motorcyclists should be allowed to endanger their own lives.
Although, if a high-speed bike-car collision can actually cause injury to the occupants of the car (I've never heard of this, but now that I think about it, I guess it might) then my whole argument is fully invalid. |
