Taxis are... not "going away". They may get more expensive. Taxi companies are simply going to make a comeback.
Uber was making it easier/cheaper for passangers - it did very little for the drivers themselves.
They can't be "fired", since they were never properly hired in the first place! They were never regarded as employees. That's exactly what this legislation is setting out to change!
Your post makes zero sense, so I'll keep it short for you. Uber was the middleman, and without it - both individual drivers as-well as taxi companies have significantly more leverage over the consumers, and can now start charging higher prices.
So how does a driver get clients without Uber? If they can get clients without Uber, why did they use Uber?
How do clients know they can trust a driver? Taxi, OK - a taxi driver has to shell out serious money to get a license. Sometimes they must show proof of training. That makes them somewhat trustworthy, especially since their license can be revoked after a transgression.
For Uber, I suppose they tried to replace that with a rating system.
Without Uber, how do you propose making it work? I suspect simply becoming taxi drivers is not a viable option for many Uber drivers - because of the time and money commitment.
