Correction Joe...according to the article the lead motorcyclist wasn't trying to wave when he crashed, but was attempting to point out a coyote on a nearby hillside, and subsequently caused two other motorcyclist riding with him to crash too!
Thereby giving me the impression that Wile E has finally switched from trying to catch the ever elusive Roadrunner to much easier prey...slower moving and uncoordinated Harley riders. Smart move on Wile E's part, I'd say!
(...I just wonder what Acme product he used to sufficiently distract the lead rider???)
