I just struggle with where we draw the line. What's the difference between this sort of scooter, and say an electric moped where the person sits (assuming the e-moped is also speed-limited)? I doubt many cyclists would have been cool with sharing the lane with an electric moped in the past, and I know I rant whenever a motorcycle or traditional moped cuts into the lanes, so not sure why these should automatically be treated different without any sort of conversation.
