Driving in the Rain

[salty9]

The other day I was driving in the rain on a 4 lane road and noticed the rain was hard enough to maintain a thin layer or water except in the tracks of the vehicle ahead of me.

Maintaining a 2 second distance I found I could stay in the relatively bare tracks. This improves the vision of drivers behind me and reduces the chance of hydroplaning. Does anyone have any knowledge or guesses on gas saved by driving like this?

Maybe somewhat less than 14.8% fuel saved:

Depends, assuming your car/tires is/are the exact same width as the one in front of you.

But then you are still pushing rain.

I use sound to help when driving in wet conditions. When you hear the least amount of tire/water noise, you are driving with the least reduction due to water.
