The number 1 easiest way to convince carbrains to support non-car-centric transportation infrastructure (in my experience)
"Giving people more viable alternatives to driving means more people will choose not to drive, so there will be fewer cars on the road, reducing traffic for drivers."
Concise, easy to understand, and accurate. I have used it at least a dozen times and it is remarkable how well it works.
Also—
"A bus is about twice as long as a car so it only needs to have four to six passengers on board to be more efficient than two cars."
A lot of people choose not to live in the city with good transit because housing is too expensive, so they live in the 'burbs. All that extra money means they can get a fancy new car lease. They drive into the city and because cars are allowed everywhere 24/7 there is no reason for them to look for alternatives in high traffic zones.
That’s the old way. There’s no real difference in pricing now until you move into the exurbs. For more and more people it’s better to pay a bit more and not have to commute while having easy access to the city’s amenities.
