The "live location" sharing situation is fucking abysmal. There are situations where it's totally reasonable that you may want to let someone track your phone in realtime - such as meeting an online date for the first time and wanting to make sure a friend knows where you are just in case. Your choices are basically "make sure you both have iPhones," "use Google Maps," "use WhatsApp," or "let some shady company like Life360 sell your location data." It's insane we don't have better options.
