Earlier quoted context omitted.
Make it simple with a 5% tax on any new bike purchased in the city. Call it the “bike lane preservation fund”.
Why would we want to make it more expensive to bike, when it's better for the environment and saves the city money as it is? Some German cities are going in the opposite direction, giving subsidies for people to purchase electric cargo bikes.
Building bike lanes is very kumbaya but these types of things are not sustainable as-is. Someone has to pay for it, why not the ones that use it? Make it great to attract more bikers and raise more money.
Or maybe just raise taxes on the place with the highest tax burden in the country? Will only chase out the small group of people that actually pay the bills even more.
I suppose we could also setup red light cameras for bikes but this would require registrations and license plates. The alternative is to tax bike sales.
