Mobility continues to grab not only the headlines but also the cash, with Saudi Arabia's Public Investment Fund making a $3.5 billion investment in Uber.
Reports say that this is the largest single investment in Uber, which is currently valued at $62.5 billion.
The fund's managing director, Yasir Al Rumayyan, gets a seat on the Uber board.
Six weeks ago Uber's newsroom posted an article called Being Uber in Saudi Arabia which said:

"The government has been extremely progressive and forward thinking in their approach by forming a committee to address both the appropriate role of this new technology in the transport sector and engage Uber as the recognized leader in the space."
Over the past few weeks there have been a number of significant announcements in the sector, from Apple investing $1 billion in China's Didi to Volkswagen pumping $300 million into Gett.
Uber itself has recently announced an investment from and strategic partnership with Toyota.
Tech giants, sovereign wealth funds and automobile manufacturers are all getting involved financially and operationally in a sector which started out as a better way to book a taxi and grew from there. In a business-school MBA thesis context, mobility is a great example of how a fairly straightforward business model can develop and mature over a relatively short period of time.
However, the elephant in the room remains questions around the profitability of the sector. Not profitability for individual investors selling out as the valuations build, but profits for the business itself. At the moment that seems a long way off.
