It looked pretty bad to me, and there was a clear "atmosphere" when Collard and Sheddon went to the podium, with them avoiding each other before they stood up for the trophies. Will have to watch it and see if it comes across on the TV interviews etc.
They didn't show the podium on the catch up I watched so couldn't comment on that, I found this on TouringCarTimes.com:
Assessing his weekend, Collard said: “It’s mixed emotions. I’m devastated to lose that win to Gordon – he drove well, there was nothing wrong with what he did. My front tyres were going off and I couldn’t brake and get the car stopped as well.
It seems that after the emotions have cooled down a little, he seems OK with it. I imagine if he hadn't taken the lead in the championship he may have felt a little more aggrieved by it. It wasn't a particularly bad nudge but it was enough to make the pass, and it wasn't the first time Gordon had done it that weekend either (although once it didn't work out for him). I know it's BTCC and there is usually some bumping etc, all part and parcel of the racing.
