Its possible that the local businesses have lost business because terminally lazy people can no longer park directly outside their shops and will not walk a short distance to them, this should be extremely easy for the business to prove if its actually true, I have my doubts its a significant amount. I suspect the people most inconvenienced by not being able to park outside the businesses are those that actually work there. This is the only remotely serious suggestion I see from the anti bike lane crowd in this instance.

My local village center is meant to be no parking on the high street, has had times its been enforced properly and times its been ignored due to pressure by local businesses. Recently they started enforcing it, directing people to the free (under two hours) car parks on the edge of the high street. Car parks were full with people who own and work in the shops, so they prevented them from parking in the car parks all day, so now they park on the residential streets off the high street enforcement area.
