It's not unusual to call a taxi for another person. Or to make a multi-stop journey where some people get out before others. You can even send a parcel across town in a taxi.
Checking phone proximity might be helpful in some cases, but it's not a silver bullet.
I never give location permissions to any app if I can avoid it (indeed I don't even have the spyware app if I can avoid it; e.g. I use the web to order an Uber)

Too many people order Ubers for other people so it won’t work.
GPS does not work everywhere, and not every device support BLE beacons.
