Why does SGI recommend learning to estimate time in seconds when judging the road ahead?
Correct answer: Distance is hard to judge, especially when both you and the other road user are moving.
Why
Distance can be difficult to judge, especially when both vehicles are moving. Learn to count seconds at a steady rate and use time as another way to understand distance ahead. The relationship between time and physical distance changes with speed, so do not treat the same time interval as a fixed number of metres.
