In Italy, few people would even consider commuting on a Campy-equipped race bike... I believe that American cycling habits stress bikes more than what they were designed to do.
Of course, that does not mean that it would not have been better if Campy had got rid of that stress riser in the spider a little early than the 1980s... According to Daniel Rebour, Campy cranks started failing as they went from the first model with the thicker arm to the thinner arms in an effort to reduce Q factor, around 1962 (for the source, check the CR archives).
But when a true problem appeared, like with the early Ti BBs, they did redesign them rather quickly...
Just for the record, does anybody know whether Fignon went down because of a crank or a BB failure? Most failures in races in Germany that I remember were BBs, not cranks... -- Jan Heine, Seattle Editor/Publisher Vintage Bicycle Quarterly c/o Il Vecchio Bicycles 140 Lakeside Ave, Ste.

Ti BB spindle failure, definitely. Sheared off just about flush with the left-hand BB cup, IIRC. The scary bit is that it was probably the later-type solid Ti spindle..... I'd wager that incident had a lot to do with Campy's withdrawal of the SR BB from the market (if my chronology is correct...).
I don't believe Laurent broke any bones in that incident, but I'm not 100% sure about that aspect of it. He was mightily upset / dejected over it, that's for sure. The picture of him literally sitting in the road, looking down the course as the other leaders faded into the distance, with his left crank and pedal assembly laying in the gutter, is very powerful indeed.
