It is pretty rare that a cab drives around with his doors un-locked. I almost always have to tell them where I am going before they unlock the door.
Another pro-tip: many times Lincoln town cars will take you like a taxi but they are not allowed to pick you up unless you called for a car so get in before negotiating the price
I recommend people never take a non-yellow cab. They have far fewer regulations, so they can charge ludicrous amounts. Even if you negotiate a price beforehand, it might surprisingly change when you arrive.
Agreed. I took one of those black Towncars once, and the driver tried to charge me something absurd at the end of the rather short trip. I told him all I had was a twenty, didn't get any change. That was the first and last time I'll ever hail one of those.
Negotiate through the window before you get in, they have set prices based on "zones". Those towncars are roughly twice as expensive I find. I Don't tip those guys since it they are doing it without the dispatcher's knowledge so it's pure profit for them
