The bike lanes here in the AZ suburbs are full of dog walkers, joggers, etc that shouldn't be there and the 20mph speed limit is designed to protect them. (Though they are breaking the rules, I'm glad that they are outside, being active). I also believe that 20mph is too slow, but I don't think the law will change in our favor.
