I have a simple question:

What does "speed limit" mean?

Judging by traffic, it must mean the minimum allowable speed. Have you ever tried to drive the actual speed limit? According to the signs, it is perfectly legal to drive this slowly. But I just don't seem to be very popular doing so.

I hope that I don't get a ticket on my bike. I often find it difficult to attain the posted speed limit when not in my car.
