If I've read this right, I do this pretty much daily. Twice.
What I'm meaning is overtaking one lane of traffic, and being about 1ft-2ft away from traffic coming the other direction. It's only a small section of road I do this on, and the posted limit is 50mph, but usually the traffic is moving around 30mph (because it drops from 70 to 50 & everyone brakes to slow down, and you get the occasional tractor slowing things down etc).
For those that know the area I'm talking about, t'is on the bridge. But if the wind is too strong there's NO WAY I'd consider it. All it needs is a short sharp gust & you're holding hands with the driver of the truck coming towards you
Saying that, when I do it, I know the risks, and accept them, still makes me nervous a little, but some nerves are a good thing!
