Maybe I am way off base and I am basing this idea on the start of 2010, and that is the only time I watched formula currently, but didn't alot of the teams, even the big dogs seem to get off to a rough start and were all dealing with little hiccups and system perfections? I mean for christ's sake Vettel's engine just crapped out on him on the first race.

We had F-Ducts being managed with legs lol.

I also thought mclaren went one race with an fduct and one with out, that may have just been strategy though as I think that was late in the season.
To me though it really felt like teams were still in a learning curve with the new machines.
So could it be this is just needless worrying anyway?
