The only...

people really doing it purely as an automotive, fully bought-in automotive other than Ferrari is Audi.

Yeah, sure.

But with Formula 1s operating, costs and income, is that significant?

Incredibly expensive if you're thinking of it as a fuel for your road car.

It's 12 to 15 times more expensive.

But for Formula 1?

There's no sleaze on the undercut.

There's been a backlash against environmental concerns.

And I think those that didn't want...

it to be true that there's an environmental potential catastrophe coming.

I've taken great solace from the backlash.

And I think we have to be careful for F1 not to be part of that backlash.

It has to still stay on the...

The morally correct route.

And I think with sustainable fuels, you can do that.

The problem with sustainable fuels at scale at the moment is that, apart from the expense, is that the enormous amount of electrical energy needed to produce it, you can't do it greenly at scale.

That would be required for the entire population.

That's something that is technically achievable.

It's just we're not there yet.
