This has been a problem for some years and leads to the overuse of red flags.  In the (good) old days red flags at the TT and UGP were virtually unknown.  Yes, bikes were slower then but tyres and brakes were also poor by modern standards.  
Waved yellows should mean slow right down until you have clearly passed the incident.  The riders know there's no sanction which is probably why they do it?
