After a long winter I finally got back out on my bike today for my first commute in sometime. I was almost to my destination when a car started to pace me. After a moment he rolled down his window and called out my speed telling me he was impressed by my speed (I was going around 25mph at the time). This is now the second time that this has happened to me and I find it kind of odd. I'm not sure if it has to do with drivers thinking we cyclists are slow or something. Has this happened to anyone else? Any other odd but positive experiences like this?
