They hate something but they don’t actually seem to know or agree on what it is. Still the fear of bike lanes is kind of bizarre. In my local town, there is a group dead set against bike lanes too. (Some locals screaming about perceived ‘property values’ plummeting because of them 
)
I was just in Montreal and was quite impressed by the cycling lane infrastructure and how much it was being used. It was so much ahead of my city, Ottawa which the segregated lane infrastructure is abysmal.
There is a town near where I live and they have taken cycling way more seriously. There are bike lanes all over the place, and also a huge MTB ‘facility’ with lots of trails and some are really surprisingly ‘technical’. It’s ‘multi-use’, but the bikes/walkers/equestrians coexist pretty well. But this town? They are making a higher effort, but it depends on the political will, and it waxes and wains. Still there are quite a few NIMBY red necks that think bike lanes are some kind of ‘communist plot’ and are determined to try to stop them using yard signs, wire, nails, broken glass, parking vehicles across them. It’s really striking how something so meaningless is enraging some people.
Bike lanes INCREASE the desirability of a neighborhood. (IMO) Bike lanes increase the options for people trying to live. (I just wish the local hypermart jumbo supermarket had bike lockers for cargo bikes. I could see getting one (N+1!) and riding to the store. (I don’t think bike racks would work well. There is a history of people walking into garages and taking bikes in broad daylight.))
