Are long boards classed as a bit shit, really vehicles under the RTA? I'm not sure that you were evading the police, inasmuch as they have no general power to stop you.
If the police want to stop you they will, although you may not be in breach of any act or statute in reality you have zero protection from harassment / detainment or even arrest if some police officer wants to fuck around with you.
