Not necessary. Let Uber and Lyft run out of venture capital and start running their businesses in a P&L world and they'll soon have to adapt to markrt realities, including establishing a benefits system to keep the people who work for them today working for them in the future.
Considering they don't plan to keep any human drivers past the point self driving cars come out, this feels disingenuous
Neither rideshare company will last long enough to see self driving vehicles come to fruition.
