The only way to get rid of it is to stop taking pool rides. Drivers need to understand there is power in numbers and everyone needs to stop doing pool rides.
Uber and Lyft will keep offering cheap pool rides to people at the expense of the driver; solidarity is the answer, drivers in every city should stand together against the pool. If no one is taking it, riders will stop using it.
UberX rates aren’t the best, but the pool is worse. If that pool ride doesn’t come with a surge, don’t take it. With surge on a pool ride, you can make a decent amount of money picking additional riders, without surge you are taking a voluntary pay cut and working extra hard for no reason.
