motorcyclists absolutely do not fall into the same category as pedestriants and bicyclists.
Pedestrians and bicyclists should get preferential treatment since they are clean mode of transport, and relatively safe on their own. Pedestrians and bicyclists are not zooming around at the same speeds as cars.
If we were all to convert to walking or bicycling that would be great and very safe. If we were all to convert to motorcycles, they would still be very dangerous. There is no getting around the inherent danger in riding motorcycles.
