In america, cars get better mileage than the official numbers. I think this is because they test it with the AC running nowdays. It was one of the gimmicks the government came up with to force cars to get better mileage without changing the official CAFE requirements.
In the past, I found real world US mileage figures to be overestimated for automatics and underestimated for manuals (coasting is illegal though - I’d NEVER do that).

You must be that slow guy in front of me! LOL. My car doesn’t even get close to the EPA mileage.

The A/C change had to do purely with Cadillac ,, they had a trigger set in the engine computer back in the 1980’s and early 1990’s that would run the engine just right for emissions testing with the A/C OFF .. the car ran like crap ,, drivability really stunk but it passed the emissions tests ... with the A/C ON the computer ran on a totaly different fuel and ignition map and ran fine but flunked emissions ...
I drive a 2005 Chrysler 300C and get over 30 mpg highway. I was looking at a new 2012 300 and the sicker claimed only 25 mpg. Same engine, same accessories etc.
