TL;DR. Ride sharing / taxi vs car ownership breakeven is at €10 per short trip (5km or less), but only worthwhile if I could totally get rid of the car: only 25% of car ownership cost is fuel, 75% or €5000 is maintenance + depreciation. my calculations (sorry if formatting is off) depreciation: 13000 purchase (5y old ex-lease car) 1000 after purchase: change of timing belt + water pump etc resale: 5y after 6000 ?? residual value 1800/y depreciation annual maintenance: 250 (1000 for 2 sets of seasonal tires every 4 years) 1000 (insurance + road tax) 40 official checkup 200 basic service (oil, filters) 1000 ?? fixing things + parking + road tolls + tickets 2490/y maintenance fuel (europe) 6.5l/100km diesel 20.000km annual mieage 1.3 €/l diesel (don't buy at highways) 1690/y fuel garage 75/m (comes with my apartment) 900/y garage total cost: 6680 €/y total cost: 0.334 €/km I also figured I do 500 trips during school year (40 weeks, 12.5 trips per weak) total cost: 13.36 €/trip This is surprisingly high. I need to find a way to make more trips :) OK, that includes holidays in which I do half of my annual mileage (10.000km) but in the end most of the cost is fixed: depreciation + maintenance. Sadly, even at free electricity EV is not going to be much better. Only 100% ride sharing will bring a cost reduction that will influence decisions.
