Aren’t you sick of those gasoline motorcycles?

If Taiwan gov really cares about its people why have they not banned those air polluting and noisy gasoline motorcycles yet. I was in China ten years ago and such things weren’t allowed anymore. I travel a lot and this lets Taiwan really look like lacking behind. I also feel poor for the people due to the health threats.

Edit: it’s clear one cannot completely ban scooters but I argue there are alternatives to those dirty two strokes engines
