I hope none of you want to die; nor do I. I'd love my family's lawyer to have video to sue the bastard for every last penny, and the city for even more for Canada's poor infrastructure; however, it'd be more proactive for craven drivers to know they are on camera. Much more likely to work than this whiny jersey. Never say 'please' for what is yours by right.
The only thing that's going to make the streets safe again in N.America (before self-driving cars) is appealing to drivers' base emotions: self-preservation in this case, rather than malice. Too bad we are not a civilized people, like the Dutch. For your own driving, not a bad idea to have an automobile dash-cam, videoing fore and aft. Make sure to drive carefully, unlike what we see on Russian dash-cameras, and to be discrete about who knows you have one in case you screw up.
Product plug: the Shimano Sport Camera looks like the best thing going if you get an action-camera. It even makes Japan look pretty.
