"You" is singular as a cyclist. Wearing appropriate gear can drastically improve your (again, singular) safety. "You" is plural for motorists. A single motorist deciding to own and operate a soft-and-safe-mobile will not affect your (singular or plural are interchangeable here) risk appreciably. It doesn't mean you're wrong, and you (singular) can pick your battles, but I think I'd prefer to be alive than correct.
