We can discuss about entertainment too.... Indeed the championship remains open for a little longer, but I watch races because I like races. If the championship is all that interests me I can buy a newspaper in October to see who won it..
Anyway.. a driver would smoke his tyres to overtake for lead in the race if that means 4 points (make it even more) but calmly and wisely will stay put for only 2. If it can overtake in pits (and now they have 3 pitstops to make it work) is Ok, if not, is only 2 points...
