Not quite sure what you meant, but if you are saying that you must be speedier driver because you are only getting 22-23 mpg (or mph). I would say it is because of the only 25% highway. I know I only have had this car for 4 months but from the driving I have done, this car gets much better gas when in constant motion rather than stop an go (even at low speeds). I have watched the ave. speed (and average mpg) gauge go down as much as 1 mph (ave speed) just sitting at a long stop light. And just going out of my subdivision, which is less than a mile, it can take .2 mpg off my average mpg.
If you were referring to average speed of 22-23 mph, then I think I get what you are joking at. However, your computer calculates stop lights and pauses in driving which realy reduces your average mph. If you are drving 75% non highway driving then getting a high mph is hard to do. If I am wrong on both, I appoliges as it is late and I am tired, but was still trying to figure out what you were saying.
Latka,
I was joking that an old guy must be driving like a kid. Most of my driving is around town so your info is helpful. I will calc mileage without the puter and report back. Thanks for the info.
