Thanks for looking that up.
I once passed a group of 30 or 40 bicycles (roadies) struggling uphill on a highway (single lane either direction, no centre dividing line). You should have heard the swearing and yelling from the cyclists as I passed (safely). From their hostility, it was clear that they were under the belief that they had the right to take up the entire right hand side of the roadway (although stretched out, there were areas in the group that were riding 4 or 5 abreast).
I don't have anything against cyclists, but they need to move over and allow vehicles to pass.
scooter style e-bikes should be banned.
I have frequently had to deal with groups of cyclists, in both Halton and Caledon, who think that they are running in the Tour de France and refuse to turn out to the right. Cyclists, and especially eBike riders, seem to be woefully uninformed, when it comes to the law.
As to the insurance issue, I would pursue it like I would an incident with a bicycle; try to file a claim with the cyclist's home owner's/renter's policy. Barring that there is supporting information to indicate that the incident was caused by someone else, and so hopefully would not be considered an at-fault.
