It would make a lot better sense to compare a GT or other bike races to the 24 hours of Le Mans than to the F1 though. A lot more riders with different experiences, backgrounds, equipments and team setups riding against each other for longer periods of time plus the weather also plays a bigger role in a 24h race than in a F1 race.@Samu Cuenca
Safety in F1 has improved considerably. As for us now agreeing something could be done in pro cycling too. That is good enough for me. This is a huge leap forward from saying nothing can be done. As once all parties involved agree something could be done, then things will get done.
A crash like the one on stage 5 will always occure, cause there's no way to stop riders from touching wheels in the peloton, unless every race is an ITT, and even there riders sometimes collide with each other.
