> That's not possible with Uber - there is no price negotiation - only declining/accepting a ride.
That is price negotiation. The market price changes all the time in response to supply and demand. If you're not willing to do it for a lower price and someone else is, you lose business to them. An hour later there is more demand and you can get some business at your price. Or you can lower your price (accept both rides) and get business both times.
Narrowing the choice to "accept or reject" isn't really removing the price negotiation, it's just simplifying it down to what it inherently always was to begin with.
> Similar argument for changing toppings on a cake - a caterer can negotiate changes to the cake - an Uber driver has no such flexibility.
They get to choose what kind of car to drive, where to buy gas, what hours to work. What would you say is the equivalent thing they don't get to choose?
> Regardless, given corporate (human?) nature is to leverage any power differential to self-benefit, it seems reasonable that regulations be interpreted in the most protective (of the party with less power) manner possible.
But what does that even mean in this case? Isn't the party with less power the one that would be out of work if reclassified as an employee, because employees have less flexibility etc. than contractors?
