Thanks Louka.
I've also been been managing McLaren and I named my player Eric Boullier
Yes, the fuel spikes could be because of hybrid mode. I've never seen that in the game before so that's why I might have been confused. Is hybrid mode when you see that fuel charging symbol next to the driver name in the race? It's not due to being overtaken as none of my drivers have finished a race a lap down. I prefer to do short length races because I have little time to play so short races with realistic pit options for AI.
I'll let you know how the next vote goes. If it still shows that I abstained if I vote for or against. Even if I voted against at the last vote it wouldn't have made a difference to the outcome so I wasn't too worried about it. But if it happens that it can impact the outcome I wouldn't have been very happy.
UPDATE: The voting by player is now working for me. I just used two votes to go against the introduction of refuelling in F1 and it counted both my votes against. It was important, as the vote against won 5 to 4 so my extra vote made the big difference. Very happy..
