I'm a woman that's done some doordash and uber. I found doordash to be a little more worth my time and effort. Sometimes I was making $17-18/hr, sometimes it was barely $10. Best times are weekend evenings and lunch time. Not worth trying to do a shift through the afternoon or morning hours. Just catch those rushes. As far as safety, I delivered to some of the sketchier parts of town but never once was made to feel unsafe. Never had any incident. Of course mileage may vary with the safety aspect, my experience may not be yours.
