I’m talking about the impact on the drivers, not the waiting time of riders (though that would also become longer on average for men, (edit: it does not change waiting time)).
I ran a simulation study of the queuing+matching system described (a variation of M/M/c queue) and there is a clear negative impact on male drivers. There are three situations: too many riders, balanced demand, and too many drivers (there’s also zero demand but we’ll ignore it).
Too many riders: in this situation men and women+ perform the same because the matching rarely happens. Women+ riders match to women+ drivers 23% of the time. Fares for women+ drivers are 53% women+.
Balanced demand: women+ match 23% of the time, yielding a benefit of 5-9% more fares to women+ drivers. Women+ riders match to women+ drivers ~41% of the time. Fares for women+ drivers are 80% women+.
Too many drivers: Women+ always match in this situation, making 5.5x more fares than men. Women+ riders only match to women+ drivers. Fares for women+ drivers are 85% women+.
The disparity can in theory go up to 8x more fares for women+, but the scenario where that happens has women always available in the system.
The actual outcomes of this would vary in real life of course, and queuing theory isn’t really my thing. I assumed all women+ drivers opt in (because why wouldn’t they?) and I’m using Lyft’s own published numbers. The state of the system will oscillate between these outcomes, but in theory it should skew towards the two biased results.
Now to your point: obviously women raped and financial impact to men are two entirely different things and we can’t even begin to compare them in this way. Rape and sexual violence is abhorrent and we should take actions to reduce and stop it, the question is always: which actions are reasonable and fair.
This system is financially biased against men, and significantly so. It would reduce the event of sexual violence (by reducing male-women+ interactions). Is the system a fair tradeoff, I don’t know. My gut feeling is that I don’t like it.
