This is one of the reasons I'm excited about self-driving public transit vans. Of course, we'll have to figure out ways to keep women from being assaulted in them if they serve routes where 0-2 occupants is a common load.
Wouldn't those self-driving public transport vans be rather exposed to vandalism in deprived areas? And it's not just women who need protection from assault. I expect that in most countries, a majority of victims of violence are men.
It's partially a social justice issue, as we've managed to build up much of our country in such a way that walking and public transport are geometrically impractical, so poor people would be trapped at home if we banned them from driving the ill-maintained car they're barely able to afford to own and unable to afford to maintain.
