I don't think Uber make that problem any worse and it's possible they're slightly safer because the drivers are registered and tracked by a foreign firm with a reputation to protect.
The people who are at risk would mostly be getting other cabs or auto-rickshaws with the same pool of drivers.
Really its the attitude of society to this stuff that's the key. India is getting better, but it's still regressive compared to the (far from perfect) western world.
More generally Uber are astonishingly better than their local Indian competition. You really have to experience Ola Cabs to know what hell is (and then experience their local counterparts to experience what hell could be if it were supported by Microsoft)
