Bicycle Stopping Distances
In a head to head test and in normal conditions a bike should be able
to stop faster than a car. But that includes that the rider has both hands on the bars (and brakes) which is hard to do when you're flipping someone off. At 50 kmh http://www.exploratorium.edu/cycling/brakes2.html Bike stops in 10 meters http://www.forensicdynamics.com/stopdistcalc Car stops in 14 meters. I hate proving Kunich wrong (again) at the expense of proving Magilla right. But Kunich may be right on an empirical basis. It make take several hundred meters to slow his fat ass to a stop. Besides this is all theory as we know Kunich has never gone 30 mph on a bike. |

The missing factor is essentially reaction time, which probably explains how Dr. Evil managed to whomp two riders with his trunk. Here's a claim that reaction times vary around 0.7-1.5 s for drivers in braking situations. That suggests that if the Doctor swerved and braked fast enough, the riders would not have had time to react before hitting the car. He's effectively got about a 1-second head start on braking, and at 50 km/h, that's about 14 meters. In other words, the car could be at zero km/h before the riders got to their brakes, and the rest depends on how closely in front of them he cut. Considering he seems to have been trying to injure them, I'm going to guess really close, like 5m. I figure that scenario as being 14 metres of stopping distance but about 24 metres of rt+ideal stopping. In other words, physics says those cyclists were gonna hit the car no matter how good their brakes, as long as their reaction times were within human norms. Gerbils or monkeys may have better reaction times than humans, though. -- Ryan Cousineau http://www.wiredcola.com/ "In other newsgroups, they killfile trolls."

In other words, physics says those cyclists were gonna hit the car no matter how good their brakes, as long as their reaction times were within human norms. Gerbils or monkeys may have better reaction times than humans, though. As usual, those who fail to think do the most talking. The brakes on a modern car will stop the car at a rate of about one gee. Race cars commonly brake well above one gee. Moreover, car tires, which cover a large portion of the road and put more square inches of rubber on the road per lb. of load, are less susceptible to road conditions, gravel etc. on the road and other traction problems. Because of the high center of gravity a bicycle has, the braking force you can apply while sitting normally on the saddle is about 1/2 gee. Got that? HALF the braking force of a car. You can increase your braking force to perhaps .85 gees by sliding backwards and putting your stomach on the saddle. This unfortunately greatly decreases your control of the bicycle while increasing your ability to brake by lowering your center of gravity. Note that normally the time to slide back like that would take more time/distance than the slightly improved braking would justify. The reaction time for both the driver and the rider are the same and so can be ignored when discussing stopping distances at equal speeds. |

I hope he gets a few years just because the man bites dog angle will generate a lot of coverage. However as we all know it's more prudent to run over cyclists from behind if you want to avoid the legal tangles. In fact it might be one of the easiest ways on the planet to kill someone without consequences. |

Huh? How can the driver's "reaction time" be relevant what he has nothing to react to? Exactly, at least in the case in discussion at the moment. In general, however, that is true. -- tanx, Howard Caught playing safe It's a bored game remove YOUR SHOES to reply, ok? |
