A SHT does not belong on a footpath because it travels faster than walking speed and is big and heavy when compared with a person. It is a hazard to pedestrians.
On the premise that roads are for moving people on all types of conveyance, I would classify a SHT as a slow moving vehicle (just like a bike).
I also think 8,000 CDN in fines is crazy and would hope that a judge will talk some sense into the local police.
