I have hit 54 mph on a long descent on an unmotorized tandem bike. We need objective and clear rules, separate infrastructure. Pay attention. Ebikes aren't killing 7,000 pedestrians per year.

And, if I strap a JATO rocket to my car, it can go over 300mph. Yours is an intellectually dishonest example, since you've decided to be so snarky. The average person on a flat surface goes about 12-22mph, sustained.
