@dalias @seachanger someone's got to write that app and run the databases. Part of me has no idea why this never happened, but I also know that Uber does a spectacular amount of IT work, they make decently large contributions to Golang (just, they're large enough that this makes sense for them), so maybe there's something about the problem I don't understand.
There's also places like remote-ish FL suburbs, that have no taxi service. There's limos, that's about it.
