A scooter has the primary brake on the same hand as the throttle. It is natural to roll off the throttle to reach the brake lever. A scooter has no control lever on the left hand. A bicycle has the primary brake on the left hand, so there is no natural inclination to release the throttle before braking.

Gas powered Vespa style scooters absolutely have a control lever in the left hand. Check out the instruction manual: https://www.vespaforum.com/manuals/Vespa/LX50/LX50%202%20Str...

I’m not talking about little electric folding scooters. I never mentioned those.

49cc scooters have the same controls as throttle equipped e-bikes. One brake on each side, and throttle on the right. The only difference is that rear brake on the scooter is on the left.

The main difference is that the ebike is arguably safer since you can’t apply throttle and brake at the same time due to the cutout.
