A push from air ??

[trikkonceptz]

Well the other day on my way to work I was cruising @65mph in the right lane when a trucker wanted to have some fun with me. He pulled up so close behind me that I could safely count the bugs in the grille.

Funny thing though, without any further acceleration I began to speed up, so I let off the gas to maintain my speed, but was the wall of air he was pushing, actually pushing me?

Curious ..

Or did he become your tail?

Safely? Easily maybe, but I wouldn't say safely. It was extremely dangerous of him to do this! The proper response is emptying your change tray through the sunroof. If you don't have change or a sunroof, periodically turning on the washer nozzles works wonders.

I wouldn't experiment along these lines any more

But watch what happens when one of them passes you, it's a similar effect.

He was filling your low pressure wake, and you were taking some of his nose pressure off. That's why 2 vehicles travelling together have less drag than the sum of each travelling individually.
