Ride-sharing app Careem has been one of the Middle East's most successful tech start-ups, and competitor Uber is now reportedly interested in an acquisition to widen its own presence in ther region.

Hosts Mustafa Alrawi and Chris Nelson discuss Careem's future in this week's episode of the Business Extra podcast. Also in this episode: Tesla adds a criminal probe from the US Department of of Justice to its growing list of problems.
