The ones that have electronic indicators fitted seem to mostly be used to indicate that the rider has no idea what that switch is for.
(I passed one that was blinking away on the pavement earlier. Looked like the rider had parked it, but failed to end the ride on the app, so the scooter was still powered up with lights and indicators going.)
I certainly find them twitchy. Much more so than, say, an M-type Brompton. OTOH, I have a lot of bike riding experience and very little scooter experience, so maybe you get used to it?
