[Formula One racing looking after Jackie Stewart in 1968] was not so intense and, yes, it was much more dangerous - what was definitely different back then was the level of safety.

Technology will have moved on to an unimaginable level in ten years.

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.

That is again a romantic notion: the hero. I think people enjoy a much more levelled playing field where you have the ability for many people to become heroes.

The arguments of waste are heavily overdone, because what you do is to accelerate the infrastructure that you have to build anyway, like airports and roads, and in this case it happens much faster. So speaking of a roadmap, without being specific, I would still go for Asia, Latin America, Africa and the Middle East - that's what our clients are really interested in.

You could think about Vietnam and at some point in time about Nigeria. And then you head to South America: Argentina, Columbia, Peru. Probably not all of them will have an F1 race, but they are definitely considering events.

F1 is a fight for people's time. There are millions of options today for how to spend it. That is probably the biggest difference from 1968 to now.
