I recall another recumbent trike rider in, I think, California, who was ticketed because the law required that he be able to put a foot down when stopped. The law doesn't require that you do put a foot down when stopped, and on a trike he had no need to put a foot down to hold up the trike, but the law says you have to be able to put a foot down when stopped.
In effect, faired trikes, Ordinaries, and tall bikes are illegal there.
But again, the probability of enforcement seems low.
