Every so often, I come across a speed limit that is absolutely out of place. I'll nominate the 30mph speed limit on the Southeast Freeway right here in DC, otherwise known as 695.
Note that this is an elevated highway cutting though DC, yet it has the same limit as the surface streets running along it. I will concede that it is a temporary limit due to construction, but I haven't seen a single worker on that piece of highway in at least two years now. Yet, the 30mph signs stand, proudly touting that fines are doubled as people whiz by at 55+.
So! Go right ahead and name some ridiculous speed limits!
