Near Espelo you are driving 50 km/h on a dry road. A cyclist unexpectedly crosses. About how many metres do you still travel before you start braking?
About 3 metres, almost all of it is braking distance after that
About 1 metre, because a reaction second is one metre
About 14 metres, more than half of your stopping distance
Explanation
False — you think the reaction distance is negligible. At 50 km/h you travel about 13.75 m during your reaction time, almost as much as the braking distance of 12.50 m (Book p.125-126).
