Cool to see that the app is just a nice wrapper to query OSM data and not using yet another dumb silo. Its also just a webapp and not a native app spying on your data. https://en.stnameslab.com/american-search-app/ is the app.
I wonder if this would make sense as a https://mapcomplete.org/ layer
If it survives a month you can buy another $500 clunker instead of losing the same to a new car loan, though they are far more rare these days (the example clunker typically now costs closer to $2-$4k now, or ~4 months of new car loan payments that you'd be stuck paying for 6 more years). The sweet spot is 10-15 year old cars under 200k miles and using small loans if you can't pay cash. New cars are for idiots and the financially independent, but newer cars 5-10 years old can be worth the price/stress tradeoffs for some once you can afford one.
You'll also get far more savings primarily riding a bike (and ebikes make this far easier once you can afford one) since most of your trips are likely under 5 miles, and your old car will last a lot longer for when you really need it. You might even find you can get by without owning a car.
