I wasn't talking about a long-distance race like the Tour de France. This is average speeds over a one-hour period. If an ordinary cyclist can reach those speeds, even for just a few minutes at a time, then cars need to be equipped to deal with it. The fact that an e-bike can sustain such speeds over a longer interval doesn't fundamentally change anything.

The average speed over the TdF is completely irrelevant, they cross the alpes. Generally on a race bike riding at 40kph if you have a slight tailwind is very doable over extended periods. If you are riding in a group of riders riding along at 40 is very straight forward, you can easily go over 50 (the fastest TdF stages are around 50 average over more than 180km distance. I can easily ride 30km/h on a regular commuting bike over extended periods (and I'm currently quite unfit).

  30 is pretty easy to do, 35 is significantly harder and 40 is insanely much harder. People saying regular bicyclists do 40-45 kph seldom have much experience on bikes. And someone going that in city traffic, like a lot of ebikes do, is just not a thing =/ too much stopping/starting and with dedicated lanes you still have to slow to traffic. O ly ebikes get up to those speeds in that encironment
