       I'm going to try _a thing_. There are two related phenomena regarding #cars and #PublicTransport that I basically never see discussed. I wrote an article about these two things which includes two very clear definitions. I want to see if I can get some reach to disseminate these two things like a mind virus.Boost if you like. Or don't. I'm not your boss.The premise: when you own a #car, it is cheaper to drive the car. But: we want to get people out of their cars, even while they still own cars.The definitions:- Sunk cost discount: for as long as you own a car, it is cheaper relative to public transport to use that car for individual journeys, even though you would save money if you got rid of the car and exclusively used public transport.- Trip cost scaling problem: for each additional passenger taking a journey together, the cost per passenger becomes lower when travelling by car, but higher when travelling by public transport.The article: https://www.carmenbianca.eu/en/post/2023-07-27-the-sunk-cost-discount-and-the-trip-cost-scaling-problem/Shamelessly tagging @notjustbikes @TheWarOnCars @ianwalker #cycling #bancars #urbanism #train #bus #metro #tram #SunkCostDiscount #TripCostScalingProblem

       Oops. Reminder to self to proofread. The public transport cost per passenger doesn't increase when travelling with more people. Rather, it stays the same! It's the total cost that increases.

       @carmenbianca A solution is roadpricing, which can level out the trip costs.

       @sorenhave @carmenbianca Yes, partly. But roadpricing does not alleviate the trip cost scaling conundrum. But it does of course make it less attractive to drive alone.
