Personally I don't like seeing the cars get slower and slower. I guess those who are satisfied with that level of performance are luckier than me.
You keep comparing random engine times. Ten yrs ago V10 engines were at the peak of that particular evolution. At the start, in 2000, times were similar to what we're seeing now.
Last yrs GP didn't have much faster lap times when they could drive the cars with considerably more confidence. Did you complain last year that times weren't as fast as 2004, or is it just a convenient stick to bash the current state of F1? The fastest lap at the first Albert Park in '96 was as a second slower than yesterday. So would you say it has gone nowhere in almost twenty years?
Engines are getting smaller and cars are maintaining a status quo in times. That's technology and smart people being smart. We only had tinkering the last four yrs and look where it got us - some very dull swathes of races. If you're only appreciating the sport for pure speed, as someone else said, go and watch drag racing. It's like complaining that, becasue you're a titty man, Miss World's boobs aren't big enough.
