I like it. Wonder if it worked.Perhaps I could have one along the lines of "This road has a speed limit of 7km/h and I live here. Please stop trying to pass me so that you can rush to the next bit of your commute"I think that may be too big, even for a Bakfiets.
I could use that sign, too! Along with "Don't try to push me out of your way. I am trying to get "there", too."
Yes, I also think there are many things to be said when you ride a bike in a city, like mine, where most people use their cars all the time and think a biker is a real nuisance!
