Assuming that 'sharp curve' warning signs don't apply to me because I'm on a brick. Sometimes that sign actually means, "This is a 90-degree dogleg, so slow f**cking down, you idiot!", which I learned last week when the road right-angled like a t-square and I found myself blowing right through it at 35mph and trying to decelerate on the pea gravel path that went straight. Fortunately, I didn't lose control and there was a path there, not 60 foot cliff.
In the future, though, I will take hairpin warnings more seriously.
