Have lived and cycled extensively in Tucson area since 1978.
There may be a few inconsiderate drivers, but you will find them anywhere.
Knew 2 ladies that rode tandem in Tucson. They got tired of close calls and yelling and even once getting patted on the butt while pedaling on Speedway.
Rear rider now wears pistol on left hip; very visible and very legal. No more pats, no more yells.
You do not need to buy a real pistol . . .
