It's way too much to ask a driver to risk driving in some gang land area or pick up riders that in way too many cases are violent criminals.

If you pick up random strangers in "bad" neighborhoods as a private person you are insane. Somehow taxi drivers are bad persons when they don't.

Do these things full time you will sooner or later get in trouble.

Going after drivers is going for the symptoms rather than the cause and quite selfish. If I wouldn't do it myself I don't want anyone else being forced because they have lower income than me.
