If you drive for Uber, you presumably agreed to some kind of contract where it's OK for them to track your every move. Drivers who only work for Lyft made no such agreement with Uber. That's probably what this will hinge on.
"Hell originated after Uber created fake rider accounts on Lyft and used software to trick Lyft’s system into thinking those riders were in certain locations. This allowed Uber to see the eight closest available Lyft drivers to each fake rider."
That's probably going to cost them one way or the other. That's actively interfering with both Lyft and the driver.
IANAL, but that sounds a lot like "tortious interference" and maybe more.
Lyft, itself, on the other hand, has a much better case against Uber
