Doha Taxi's

I was recently in Qatar and had to take a taxi back to the airport. they have a great, albeit somewhat big brother, taxi system. the attached screen is in all Qatar Taxis. it has the name and picture of the driver, where you are, where you are going to, how much the fare is.... so far so good.  what makes this different is that the taxi is using GSP to know what the speed limit is and tells the driver to slow down if they are speeding. it also puts up a big red flag on the screen. if you exceed the speed limit again they you get a second warning. I don't know what happens the third time he backed off his speed after the second time.
