i will give example with my 1962 MZ ES 250 motorcycle:
You will stop it less distance when alone but with a passenger, the weight distribution is probably what is making the bike \"feel\" more balanced. Extra weight will hurt your stopping distances.
Lesser rolling resistance on bike is a factor but no way near as important as the huge advantage of lesser drag.
I know. I was making the point that aerodynamic drag isn\'t the only factor. There are many factors that contribute to drag. I used rolling resistance as an example. I could have used drive-line efficiency since a bike has less parasitic loss in the drive-line compared to a car (going back to golf3diesel\'s example of 200hp car vs 200hp bike). The bike puts more power to the wheel.
Thats not entirely true, sure a heavtyier car could do it faster,, but its also in the type of equipment you use to, No Rolls Royce Phantom is gonna decelerate faster than a C4S at the same speed, even if it is 2800lbs more..
You\'re missing the point. The heavier car will take longer to slow down. That\'s why the heavier car will be \"in front\" of the lighter car (in GT\'s example). Also, in GT\'s example, both cars were identical and GT\'s example stated that the heavier car would NOT decelerate faster. Reread the example GT gave. The heavier car will take longer to slow down which is why it will be \"ahead\" of the lighter car.
