yes, speed is definetly relative...case in point: i once drove a 1964 Buick LeSabre with a 355 Wildcat V-8 engine. one mean machine. my brother-in-law has a 1969 Firebird Convertible with a V-6. much smaller, but still fast. he challenged me to a grudge-match drag race. i did a 16 second 1/4 mile (about 120mph) and it really felt like i was going about a million miles per hour. needless to say, my car died soon after. but now when i ride with my bro-in-law, and HE does 120, it feels even faster, because his car is open, and my Buick was not. so i am inclined to think that MF may feel a lot faster than 92 mph because of the train design, the trees rushing past, etc....
