The best way to get people on board with more bike infrastructure is encouraging ebikes and escooters. In my city, 50% of the bike lane traffic downtown is Lime Scooters--people who would never own or commute with their own bicycle. Suddenly these people have opinions on bike infrastructure and will be more likely to vote and support improvements.

In short, if you want your cities bike infrastructure to get better... encourage the city to embrace point-to-point scooter/bike rentals.
