Lots of people take the new white taxis because they have metres and they think they're avoiding the hassle of arguing with the black taxis that don't have metres. Ha ha, think again! I have personally been in a white taxi and the driver cheated me. He did something with his meter to make it read more than the price actually was.
How do I know this? I took a taxi from home to work many times and the cost was always around 15 LE on the metre. then one morning I got into another white taxi and the price was over 30 LE. The exact same distance I take every day and it was even faster this day because there was absolutely no traffic. I started arguing with the taxi driver and when he could see that i could speak Arabic and I told him I take a taxi here every day and the metre is never that much he very easily said okay give me 20 LE. Obviously he tampered with the metre because no way in hell would anyone accept less than what's on the metre especially more than 10 LE worth.
Beware cheating is everywhere
