Fuel Saving Tips
Driving in the far right freeway lane puts us in conflict with cars entering the freeway. Here's how to know if you're going to collide. The sailing term is called "ranging". You compare the nose of the vehicle to that of a non-moving background, like a freeway wall. If the nose of that car remains static to the background you are on a collision course. In this case, you should slow down. If the nose of that car is visually "eating" the background, they will merge ahead of you. If the nose of that car is visually "giving up" the background, they will merge behind you. Doug in Oakland, California USA
