for about 2-3 block distances I've been known to push high 30s...problem is I have all of no power at all right after.
Actually I done this today to make it to work on time...had to get to the sensor area of the intersection so the light stayed green (6 min wait if I miss it)...problem was I had to make it over half a block in a rather short period of time.
Man that was fun...but it really took it out of me. I also think I freaked the lady in the minivan in front of me out pretty bad when I was pulling up to a van in 25-30mph traffic. I was basically right on it's butt all teh way to the intersection.
Also a short fat guy here...my normal cruising speed is about 16-20 for what it's worth.
They need smoother roads there though...the crappy pavement they have in some of the areas out here is not sprint friendly.
