7. A city ordinance stipulates that all bicycle riders must wear a helmet. Bethany decides to enjoy a cigarette during a leisurely Sunday morning bike ride. As she goes to light the smoke, the chin strap on the helmet pops loose causing her to crash into Melanie, who is enjoying an enormous lead in the annual town-sponsored 5K run. No one is seriously injured, no property is damaged, and the 5K does not offer any sort of prize, but Bethany later learns that the bicycle helmet has been recalled due to a defective chin strap lock which has caused several hundred serious injuries throughout the country, including 22 fatalities. Does this scenario present a valid tort claim involving Melanie and/or Bethany? Why or why not?
