Men only Taxi Company

I bet you read that and thought "that's sexist" well why then is it OK for a Female only Taxi company to be set up?
The service, Angel Cabs, will employ only female drivers, "in a bid to make people feel safe as they travel by cab throughout the city" ??????????
The way they plan to operate is for the "Angels" to pay €40 to have their name and mobile number advertised on a site "www.angelcabs.ie" (they say it'll be online from March) and passengers will then ring them directly.
Somehow, I don't think this will work.
