The article sounded like the proposed bike tax is targeting any bike. Either the biker enthusiasts they quoted or the article author (or both) could be purposely misleading.
(Disclaimer: Personal bad experience with bicyclist)
Some nut in our neighborhood rode his bicycle on the normal driving lanes, instead of using the designated bike lane.
During rush hour.
Which he tied up the traffic, other cars of course then tried to change their lanes dangerously, almost resulted in several accidents.
