I think the author is slightly exaggerating here; not that the larger range wouldn't be useful. Assuming that there's a stationary obstruction that you must come to a complete stop. According to [1] the stopping distance of a car travelling at 70mph is 245ft (75m). A car travelling at 70mph is doing approx 31m/s. With a 0.5s reaction time, the car would travel only 90m, or;
With a 200m range, the car would have 4s to initiate an emergency breaking manoeuvre. [1] http://www.government-fleet.com/content/driver-care-know-you... |
