I made up a game called “mortar”. Pick a distant object that you feel is X seconds away and see how close you can come to hitting it. You can play solo or with other passengers in competition or just fun. You need a digital watch with seconds
This works particularly well on long drives where you can get shockingly good at it. “Level one” is to pick an object when you feel it is exactly 1 mile away. “Level two” is to pick an oncoming car that is one X-mile away. “Level three” is to look down and to quickly do simple math in your head for adjustments in your speed (e.g. 82mph – how many seconds to 1 mile out – and where is that exact spot).
It gets fun when you start picking objects that are not visible – say a car in a dip, or adjusting for large bends in the road.
Level four and beyond is Jedi master stuff. Such dangerous information cannot be divulged here to the untrained.
I don’t see why this wouldn’t work in traffic.
