PMDs should never be allowed on footpaths in the first place. The PAP's dilly-dallying banning it on footpaths led these Ah Bengs and Ah Lians to believe that it will never be banned. It has also led to deaths and serious injuries to pedestrians.
Just allow them on the roads like bicycles. Plus licensing, insurance and enforcement and speed limits. Problem solved.
Pedestrians on footpaths heypi, PMS riders heypi.
