If only a single point were given for pole or fastest lap, then that is unlikely to decide a championship. If a single point is all that’s needed to mathematically eliminate the competition then sure, doing a low fuel quali-like run in the middle of a race should get you point, but it would hamper a race you were almost certain to get points in anyway, so who cares how that point is earned (perhaps there could be a proviso to say that the fastest lap can only be earned by somebody classified at the end of the race, as this wouldn’t guarantee championship victory any more than sitting in 3rd all race then retiring right at the end). I don’t know if I’d be bothered or not, but a single point for either pole or fastest lap isn’t something I’d rule out. For one thing, as I pointed out in an article, if quali is so special that it deserves it’s own tyres, perhaps the significance of pole should be recognised and complemented with a point for pole.
However, I agree that any more than 1 point would make things confusing to follow. I think even the most casual fan would be able to understand though, if going fastest ‘done gone and got that man a point.’
The only drawback in my mind would be the argument that all of an F1 race weekend is geared solely towards finishing in the best possible position, and that that is all that should be rewarded. It is a fair argument, but when a single point is only 4% the value of a race win I think one can be afforded to be given out.
Perhaps a single point could be given to the constructor (and only constructor) who does the fastest pit stop. This would add confusion, but it’s only the constructors championship, so casual fans are unlikely to care as much lol.
