I live somewhere where the vast, vast majority of taxi/Uber drivers are men.
& I've had no issues in 4 years BUT I know several women who've had unpleasant experiences.
So if a 'women drivers' initiative started, I would download the app &use it in preference to Uber.
& if no female drivers were available, I'd Uber, but I'd prioritise women driving women, every time.
If a 'trans - not for you' app were to be started, I'd wish the start-uppers & their potential client base well.
Honestly- crack on. I can't see any reason anyone could object.
It's a fight being sought with your own shadow.
