I do care about pedestrians, I walk way more than I cycle, that’s why I’m proposing a solution that will make both safe. The city would maybe spend a bit more money up front to put down some paint , but long term it would save money because cars wear down the road much more than bikes. Cars are the thing that’s draining the city budget by forcing constant road maintenance.

I don’t understand what you want , if you want bikes to stop being on the sidewalks and for the city to save money along with a bunch of other benefits put down a bike lane, unless you have some better solution. You haven’t suggested any solution though which makes me think you want to just be mad at cyclists and stew in your anger without doing anything, which doesn’t sound like a good way to live.

If you do want to get mad at something get mad at cars which are an exponentially larger threat to you as a pedestrian then a bike. Unless your main means of transport is a car and you can’t get mad at them so you take it out on cyclists instead.
