We just moved from a very rural area to a large city and am surprised at all the food delivery/rent-a-bike-or-scooter/ride-share/car-share/random delivery/etc. apps and services that are available. What do you find you get the most use of and most value for money?
Public transit. I live near where a rapid bus and train intersect so I can get to most non suburb spots super easily and cheaply.
