EDIT: Mistake, I was in Jeddah, not Riyadh.

I have never, never, been ripped off by taxis as I was in Riyadh Jeddah. I don't know if Riyadh is the same, but I wouldn't travel in Saudi Arabia again without using a taxi app.

The worst bit is that one taxi driver, I believe deliberately, took me to the wrong part of the airport. And, I had to get another taxi to international.

And, every price negotiation was a massive ripoff. I paid hundreds of pounds for a trip to the waterfront and back.
