Pardon my ignorance as I couldn't find a lot of information on this but if Uber became a transportation company wouldn't that require full-time contracts for all the drivers that would use the application? This seems quite restricting as the purpose of the app is to allow anyone to join the platform and for the driver to drive only when he feels like it.

Forcing licenses doesn't restrict the number of possible drivers? In my country most licenses are held by cartels who don't let any new incumbents in the market.

Also there are some who don't want to be taxi drivers but just do this in off time in the weekends. In my country people that drive for Uber need to have either a juridic registration either as a company or as an authorized person and since Uber has forced online transactions, predetermined pay and a review system, the tax evasion is nonexistent, there is no pay cheating and the drivers behave (as opposed to the taxi drivers who due to cash transactions do a lot of tax evasion, temper with the registering devices and don't care about customer feedback even refusing rides based on tipping).

I hope that if the legislation changes then it also brings the old system to the 21st century.
