You just discredited yourself. Everybody speeds in the US. To the point that obeying the speed limit can be quite dangerous in some cases.
Therefore, both men and women are speeding, but men are taking greater risks, speeding more. That's a problem, because a small increase in speed produces a large increase in kinetic energy. It's velocity squared:

The men are profiting by having a greater willingness to put their passengers and other drivers on the road in fatal danger. They are all breaking the law, but the men are more brazen about it.
Uber should solve this, because it is a serious problem. If you only look at the payment aspect, that is demonstrably easy to solve. Pay women more. Very easy.
If you want to solve the root problem, and not a symptom of the problem, then Uber needs to tackle the problem of drivers speeding. Automatic reporting of speeders is one approach. Another is to remove drivers from the pool of available drivers for any ill gotten time they gained by breaking the law. Save one minute with your fare because you drove 80MPH in a 70MPH zone on the freeway? Then make the driver invisible in app for one minute (or more) after dropping off the fare. There should be some cost imposed for breaking the law proportional to how fast the driver was going.
Frankly, society has a cost assigned to this already. They're called speeding tickets, and I see Uber drivers who should get them regularly.
What will Uber do when they switch to autonomous cars? Make the robots speed too? Given their willingness to break the law so brazenly as a company, I would not be surprised if this is what they do.
