Asking me to stay in such unsafe conditions is unreasonable
What we're talking about here is the time it takes you to follow a cyclist around a blind bend on a winding hill road. You appear to be saying that you think it's fine to overtake him on the bend accepting the risk that he may be knocked to his death on the cruel rocks below or you may kill an oncoming driver as you pull out.
You seem to be saying you feel as though you're forced into doing this because you're worried that the people behind you might be driving even more dangerously than you are ?
I have no idea where you live where it's illegal for cyclists to be on the road but where I live they have every right to be on the road and we have a lot of narrow winding roads as well, going downhill cyclists can actually go down them faster than cars can so the only problem is if you're behind them on the way up and even this is not a problem for people of consideration, yes you might have to slow down for 1-2 mins but then there will be a safe passing place or if not the cyclist will almost always pull over for you and let you past.
The fact your trying to justify reckless, dangerous and inconsiderate driving by blaming it on a fear of what others might do is frankly very worrying.
