One of the things I felt that interview made clear was that teams and medical staff DO care about the riders, and ARE doing the right thing.
Riders aren't being pressured to continue, and the teams/staff are stopping riders pretty soon after these incidents. From that Skujins report:
"... and gingerly continued to ride for short distance before his team pulled him out of the race. "
You or I might fall off our bikes tomorrow and get worse care than these guys. A colleague came in last week complaining of concussion; he'd just self-diagnosed TWO WEEKS after banging his head on a low beam!
Riders staggering about like Bambi to get back on the bike looks awful on TV, but really I'm not sure the riders are being failed by the current system. And as many people have said: helmets prevent concussion, don't they??
