This is a horrible proposal…

This is a horrible proposal. Bike lanes are not causing the traffic congestion, traffic does. Removing bike lanes reduces the number of people biking due to dangers of sharing the road with the vehicles, forcing them to use vehicles — and more cars create more congestions.
Not to mention the environmental benefits of biking (less CO2), health benefits (bikers are healthier -> less strain on the health system), infrastructure benefits (less damage to the road -> less upkeep)
Not to mention the biking infrastructure is already built, and built recently — and removing it costs money. Money that were spent just recently to establish it, and that could be spent elsewhere — on healthcare, for example.
