Fuel Saving Tips
The gap to the car in front should be at least 2 seconds on a dry road. And if you're the 3rd car in a line and the 2nd car is only 1 second behind the lead car, then you should be 3 seconds behind the 2nd car. Someone else may sneak into the gap you've left - let them and don't get caught in their accident. And double the gap when it's wet.
