it appears riding in a door zone is actually vehicular in nature according to the rules of the road, just not advised.
And roody, your comedic assertion you're never in the door zone in the driver's seat?
but your CAR is on occasion, roody and that's what really counts. motorists drive their cars in the door zone past other cars REGULARILY. and in a vehicular matter.
Door zones ARE part of the road used for vehicular operation of vehicles on many roads.
