Haven't any of these idiots heard of momentum? a sport bike doing 150 exerts less force than a ford focus doing 35 mph... and less than an explorer SUV doing 20 Even if the sport bike winds up to 200 mph, he's creating a force less than 1/4 that of a hummer h2 doing 65 mph. I made a simple table, units would be ton miles per hour, but that's not important, what's important is the force ratios from sport bikes at speed vs other vehicles. just as a reference I used, my sport bike, a ford focus, explorer, f150, f350, h2, peterbilt, and peterbilt with load. rough numbers linear momentum.
