A way to bring back non-championship grands prix?

[Mark]

Indeed. Having a test session on Monday, in which none of the drivers who competed in the weekends race are allowed to drive, would be a good idea!

Obviously this can't be at every track, and shouldn't be. But at the likes of Silverstone, Barcelona etc, why not!

there are more tracks than places available on the calendar

The best way to solve that is to rotate venues. Not Monaco, Interlagos, Monza or Spa, but the rest. Hungary and Russia. India and China. Singapore and South Korea. Bahrain and Abu Dhabi.

Not only we get rid of some of the boredromes, each race gets an increased value for the fans. If South Koreans know that the next edition will be in two years, people would be encouraged not to miss this one.
