When women riders and drivers told us they wanted more control over how they ride and earn, we listened. That feedback led to Women Preferences, features designed to give women the choice to ride with other women. Since our first pilots last summer, we’ve heard just how much that choice matters—from feeling more comfortable in the back seat to more confident behind the wheel.

Men have so much less reason to fear compared to women. This is not saying they have nothing to fear, but the measures taken by uber is an attempt to protect those who are MUCH more prone to sexual assault and harassment.
The fear of accusations is not covered in this survey, nevertheless, if men feel fearful of accusations, imagine what women feel when they fear actually being sexually assaulted.
I do not agree this can be assumed.
