For a concrete example of carrot and stick - check out ridership numbers for the 49 after the Van Ness BRT project finished. 49 ridership is more than completely recovered at 140% of pre-pandemic numbers. In comparison, the 38 and 38R didn't get their dedicated bus lane out in the Richmond and ridership numbers are still nowhere near pre-pandemic. Make the bus fast and frequent and people will take it.
