1. That was the first communication to Kimi on the radio and it was during the high speed corner. How would you like it if you were driving that fast through a corner and someone shouted in your ears? He told Permane that he would let Grosjean pass, but if you were to do it in the fast corner, you would have to go fast as well so you don't lose the car by slowing down in the middle of a turn suddenly. Grosjean didn't know how to pass properly, as evident in his time in Formula 1, and his whining about Guttierez in the race. Just look at Alonso turn his frustration into an actual pass instead.
I personally don't find that a reason, but an excuse. First of all, I think that if you are able to shift 50-60 times in one lap, adjust the brake bias every corner, and change several setting throughout a race, that you should also be able to handle a message during a high speed corner. Second of all, Massa was coming up. Had Kimi stalled Grosjean half a lap further, I believe Massa would have overtaken both of them. So it was urgent. I am not going to talk about Grosjean's past, that is very irrelevant to this discussion. However, the attempt from Grosjean to overtake Kimi was a valid. Kimi on top of that had all the time to let him past, but he blatantly ignored the order. For all that Grosjean did for him, Kimi should have had the curtosy to allow Grosjean through, swift and clean.
2. The minute the Kimi to Ferrari deal was announced, certain Lotus personnel started acting cold towards Kimi. This is very similar to Hamilton's announcement from McLaren to Mercedes. The reports of employees not wanting to share too much with Lewis in terms of data and also bonding because they then saw him as a competitor from another team. Remember spygate? Nobody wants to give another team technical information, which is even more important in a time where new technical regulations are going to start.
Yes, and I am sure Kimi got the same treatment when he left Sauber for Mclaren, Mclaren for Ferrari and probably also when he got kicked out at Ferrari. That isn't about 'acting cold', but about professionalism: you can't expect that a driver keeps getting vital data once it is known he is leaving. You'll get the same treatment in any company where you have mid to high level position. That isn't personal, just the company protecting its intellectual property.
Clearly, you do not know the situation at all.
Oh I know the situation, I just have a different opinion about. Now I respect yours, I'd like you to do the same.
