In any case, I don't understand why disc advocates and users don't at least demand some effort at making them safer. It's technically not difficult (though it would add slightly to cost) to improve safety by turning a semicircular edge on the discs. They'll still be thin, but at least they won't be razor sharp.
So, to the true believers, DEMAND that some (minimal) effort is made to address this safety issue.
Absolutely we do. That's why we use things like Ice Tech, to dissipate heat on long, steep descents, so we don't lose braking power. That's also why hydraulic disc brakes exist, the better modulation and reduced effort are basically safety features, so roadies with weak grip strength can still stop when they hit traffic at the bottom of the hill.
Those are
actual not
perceived safety issues. That's why they've received attention.
