This "gray zone" is interesting for two reasons in CA a class one bike lane (you know , the bicycle/pedistrian two-lane path),
What if run out of gas? Can you really hang me for disengaging the belt drive and essentilly pedal a 100lb bicycle? And what if I become overheated, can I not take off the helmet? If I run out of gas, this is my best route home (although I make a consciencous effort to NOT run out of gas). If there is no engine running, how differeent am I than a fully loaded touring bicycle? I may set myself up with lawyers & the local cops to let them know what I'm up to, take the citation and make the courts decide. Sometimes, push comes to shove so that the damn bureacrates have to take a stand.
