I'm surprised Massa and Kubica haven't been pulled up for dangerous driving.
Why would they? It's called "racing" and if you take it out from th F1, it's not worth watching anymore.
The last race made it clear that there would me a whole lot more racing in F1 if there would be less grip. That can be had by:
1) having a rain race
2) changing rules, so:
a) tyres would have less grip
b) aerodynamics would be less powerful
c) brakes would have less grip
IMO, changing tyre regulations has been worthless. Since the introduction of groove tyres in 1998 every year there has been more grip, with the exception of 2006 when you couldn't change tyres during the race (which was a good thing, except that they would have had to allow changing a tyre on dangerous conditions). Tyre companies have more knowhow about tyres than any FIA member, so FIA can never make such tyre rules that would serve the purpose. They can only enforce "a change", which teams would have to adapt, some faster than others but give it two years there is no difference.
Also, teams are "infintely" wiser than FIA about aerodynamics, so changing aero rules is not working. FIA could deny wings or such parts, but that would still not mean much. One thing that FIA could do and make sense would be denying changing the car during the season. Teams would have to give a spec car before the season and then after each race FIA would compare the race car to the spec given to them before the season. That would be cool
But still, braking is the most intersting aspect to me. Currently brakes are so great that the distance it takes to decelerate the car is close to nothing. If it took hundred meters more to make the car stop, there would also be more variance in when to begin braking. Now everyone brakes at the same spot, which makes overtaking very hard. Change regulations so brakes would lose power! That would mean drivers would have to adjust to the situation, but they surely would. After that, because nobody wants to hit the wall top speed, drivers would begin braking earlier; and that would again give drivers something to "race" about. Currently, you either hit it or miss it, but were the brakes so powerful, things would be a lot more interesting. Someone would be able to drive a turn a little faster, thus being able to brake a little later. Someone else would take it on the safe side and brake a little earlier. Those differences turn into overtaking opportunities more likely than adding one more groove to the tyres!
Anyway, this is way off-topic so I'm going to stop now.
