Yes Skip, a bicycles is not a motor vehicle. I think we all agree on that.
However RSA 265:143 clearly states that bicycles are subject to all the laws that a motor vehicle is.
Your "Drive" definition 259:24 only applies to motor vehicles. And as we have all agreed, a bicycle is not a motor vehicle.
I guess your real intension here is to talk this issue in circles so that most readers will give up and not follow what is going on. However you and I both know that you are wrong, but will not admit it.
