I ride and all I can say is Shatner is a Double DumbAss.
T-shirt,shorts and sandals? How stupid.
Helmet, boots, gloves and some sort of protective jacket.
Leather in the winter and amour mesh in the summer.
Most of the time when there is a bike crash (when the rider isn't popping wheelies or something else) it's other drivers that don't see them.
ALWAYS PROTECT YOURSELF FROM OTHER STUPID DRIVERS!!!
