They ought to give some kind of penalties for engine and gearbox changes if they want to enforce the rule of them lasting for several GP weekends. But we can be open about discussing, which kind of penalty should it be. About penalizing every racing incident. Well, I remember we had serious discussions about it already in 2008, when Hamilton got a lot of penalties and the most ridiculous one was the incident with Bourdais at Fuji. In 2009 F1 fans were a bit more satisfied as a former driver was added to the panel of stewards. However, at times we are still getting penalties, which seem like an overreaction. But I think nowadays the governing body wants to enforce very clean racing. And by enforcing harsh penalties they are somewhat achieving it. For instance we don't have such incidents any more like 20 years ago, when it was usual to see some midfield driver wiping several drivers out at the start of a race.
