Well, since I’m a man I’m not really qualified to offer solutions to these kinds of problems which mostly affect women and minorities, but there is definitely a fine line we must walk between breaches of privacy and safety. Ideally society in general would combat assaults against women and minorities but we all know how slowly that goes. More certification of drivers and harsher consequences for unacceptable behavior would help, but then that wouldn’t make Uber as attractive for a side-job as it currently is to many people, which would hurt their bottom line, so I doubt that will ever get done (in fact, they seem to be actively fighting against countries which try to legislate exactly that). It would also not help with the reverse situation (drivers being the victims).
