helmets for bikes and scooters, and knee pads/elbow pads for scooter (more because the the pads came with it and DD is enamoured of them, but they have saved a few scraped knees.) Helmets for kids on bikes are mandatory in much of Canada. I know the wind feels nice through my hair (and the helmet does awful things to it), but as my friend always says,"Helmets are sexy because brains are sexy!"
Also, Montreal drivers are insane.
