Or maybe cars should obey the speed limit, pass at a safe and reasonable distance, and not road rage at people? I mean, why does every new alternative travel mode need to work around the unacceptable and lawless US driver behavior? That all said, 25mph on scooter wheels sounds terrifying. I've seen some escooters with tiny adorable disc brakes. What's your stopping distance at that speed?

That all said, 25mph on scooter wheels sounds terrifying. Meh, you work up to it. Time and place, though; I tone it down through the downtown part of the trail. What's your stopping distance at that speed? Faster than my car or motorcycle. And that's just using the regenerative braking of the motors. I've never tried a full-on-drop-anchor stop with both the mechanical disk and regen brakes.

  > > What's your stopping distance at that speed? > Faster than my car or motorcycle. And that's just using the regenerative braking of the motors. I've never tried a full-on-drop-anchor stop with both the mechanical disk and regen brakes. Do you have a heavily modified scooter or something otherwise unusual? I looked up braking tests for cars, motorbikes, and e-scooters, and couldn't find a single e-scooter that's been tested that has the same stopping distance as a normal car let alone a sports or a motorcycle. I don't think this is super surprising considering the relative size of the contact patch and what the "tire" is made of on most scooters. In another comment, you said you have a Xiaomi scooter. In this brake test (https://www.zdnet.com/article/mi-electric-scooter-review-complete-that-last-mile-commute-with-ease/ https://www.zdnet.com/article/mi-electric-scooter-review-com...), it has a 13 foot stopping distance from 12.4mph even when using the disc brakes. This is similar to what other scooter tests show. NACTO's suggestion for a conservative car stopping distance is 11 feet from 15mph, not including reaction time, which is the same as in the scooter test (https://nacto.org/docs/usdg/vehicle_stopping_distance_and_time_upenn.pdf https://nacto.org/docs/usdg/vehicle_stopping_distance_and_ti...). How are you getting your scooter to stop more quickly than a motorcycle?

    Better brakes. The Xiaomi’s stopping power isn’t even close to the Boosted Rev, mainly due to weak regen braking on the Xiaomi. But you caught me, it’s all been measured on the seat-of-the-pants dyno. </shrug>

Drivers will pass if you’re going slow, and some of them will do it dangerously so faster scooters are a safe move. I can stop as fast as the cars do.
