Huh? You can only hold leverage in a contract, if the other guys agree to enter into the contract.

If the contract party A proposes gives too much advantage to party A for party B's liking, party B can make up their mind before they enter the contract.

Btw, if Uber is so powerful as you say, why do they bother with the tinkering around the margin and only force arbitration? Surely the bigger deal would be to jack up prices to thousand dollar per ride?

If what I'm saying isn't already blindingly obvious then more HN comments aren't going to change anything, sorry.
