What does "No Driver" mean in an escort ad?

They will be coming to your location by there owe means, usually driving themself without the benefit of someone waiting for them in a car.

can't get in your tight muffin then U help...Wink!!  LOL.

PS> I have my own car..

Yea, I do not usually  like to see girls that have a driver .
Funny story I lived in a condo unit and a buudy and me were smashed and called hookers.
Well , the girl next door got nervous at the driver sitting in the car in front of her unit  and called the cops.
Back then we had a security guard at the gate and a few days later he told me the cops had laughed and said the blonde was good looking and I don't blame the guys
