Criticism of Formula 1's engine regulations has become deafening in recent races, particularly relating to the token upgrade system and grid penalties.
There is something amusing about drivers receiving grid penalties worth several dozen places on a 20-car grid, but the suggestion that it is that confusing to fans is somewhat patronising. The bottom line is that the rules are there for a very valid reason.
On Tuesday Gary Anderson argued that the grid penalty rules were ridiculous. Yes, the number of penalties being doled out is absurd, but the blame must surely be with the struggling engine manufacturers?
