No way. Insurance and hassle are always cheaper than paying labor. My employer can bid down rental cars to $40/day or less, which is less than almost any meaningful Uber round trip. Even for a individual like me, I can get Nissan Altima or whatever for $70-80 in most places.

You also have improved safety and security for employees vs John Doe and his 2010 Odyessy Uber that is falling apart. Uber is a shitshow experience compared to what it used to be.
