The FIA did the right thing by not giving them any actual race bans, for now. And I say this as someone who just plain can't stand the McLaren team. The loathing I have for them is deep. I will never forgive them for making the suggestion for grooved tires and 10% narrower track. But, I also feel that the best thing for our beloved sport is for all the teams to be out on the track, creating action for us fans to watch.
If the McLaren team does anything that gets them in trouble over the next 12 months, I think the penalties should be so harsh, that it makes them not race for a season.
The sport needs to have integrity. The teams can't be going around thinking that they can get away with bloody murder. The possible further penalties that could be applied to McLaren's case, should also be a deterrent to other teams that might want to go the road of dishonesty. A punishment shoudln't only be about punishing the guilty. It should also prevent others from following the path of the guilty.
