In my 64 years, there has never been a place I was going to that wasn't there when I got there. And if it wasn't there when I got there, I probably had no business going there in the first place. If they are riding slow or blocking you, ride with them. Who knows, you might make some new friends. As for cars, they are bigger, heavier and faster then I am. I usually let them have the road, winding or otherwise. In my opinion, a 10 mph safe ride is better than a 16 mph dangerous one. I love riding my bikes. If it takes me an extra 10 or 15 minutes to get somewhere, then that's 10 or 15 minutes doing something I love.
