i just drove a new 2008 volvo for about 50 miles and using the radar on the front you can use the cruise control to stay a certain distance behind someone.... it was averaging beteween 15 to 19 mpg normally. Staying close behind a nomal full size truck going 65 mph using cruise control i was getting 22 to 23 mpg.

put this on a tundra and you could see a huge improvement following other people on the highway
