I like going fast as much as the next guy, but lets be real, the safety profile of someone pedaling 30 mph is not the same as someone pressing a button to go 30 mph.

When you're pedaling at 30 mph, you're much more likely to be engaged, paying attention, and under ideal conditions. Folks who cruise at 30 at the press of a button, tend to actually do so consistently. Anyone who rides on a bike path anywhere today can obviously observe the differences in behavior.
