Contractors have certain legal freedoms that employees do not, such as setting their own hours, being able to turn down work, driving for both Uber and Lyft, etc -- that last one seems pretty common.
I wouldn't expect those freedoms to last long after they are reclassified as employees. After all, this is Uber and Lyft we are talking about. We know how they behave. Now the government has both increased their operating costs and given them the ability to exert more control over their drivers.
