Being biased, I’d love a Finnish GP, even if it’s just a one-off, at some point of my life. I know it’s completely unrealistic – Finland is a very small country in terms of population, though I’m sure the grandstands would be packed. Have you ever watched a race without seeing at least one Finnish flag being waved in the crowd? I don’t think I have. Motor racing is a big deal here.
However. I don’t really like street circuits, so I’d rather see a new, purpose-built track, and that could be anywhere in the world so long as it’s an exciting track.
