Monaco was my first race of the season and I spoke with a number of people and all seemed to be very optimistic.

Why not look at Indonesia? It will be the third biggest country in the world in population in 25 years' time - after India and China.

One of the reasons why they are optimistic is that there is more competition. Red Bull has become more competitive, the races have become more attractive - and that is what fans want!

In that - and that is my personal view - Singapore delivers the most value, as they think about Formula One as a complete entertainment event, on and off track.

I interviewed Kim Kardashian recently and had a conversation with her mother. A lot of people have various thoughts about Kim Kardashian, her mother and her sisters, but it is an incredibly well thought through concept and branding. Each of the daughters appeals to a different segment of the market.

The world is changing. And a lot of people in Formula One are starting to understand this.

In the Ridley Scott film 'The Martian' you can do that [virtually driving car]. I have lifted off in the space craft from the surface of Mars, walked in space and looked down into deep space and got terrified, with the headphones and the goggles.
