Most cars can stop at a rate close to 1g (9.81m/s2). If the brakes on
a pushbike are effective enough to produce more than 0.5g you are
likely to be thrown over the handlebars (1). Bikes have very skinny
tyres compared with cars and bike brakes are very ineffective in wet
weather in my experience. Push bikes therefore have very much greater
stopping distances for a given speed than cars .

Do you have any info on the stopping distances for motorcycles/mopeds?
How do their stopping distances compare to a car?


Why would he have - does he ride one?

I would have thought it was paramount for any road user who travels
at anything much above a walking pace to know their stopping distance.

Particularly in areas of other vulnerable road users - eg children.

What do you think?


Oh - sorry - I forgot - you don't do you?

Stopping distances for bicycles do not appear in the HC ... and so
cannot be of any consequence.
