I don't know about the mojo, but the patience of some fans is at a premium.
Testing is now tight, and I wish the FIA allowed more time to sort the cars out. But everyone has the same problem, they all knew about it over a year in advance, and thus it is just another difficult technical issue to be resolved. Difficult decisions have to be made, priorities have to be mapped out, and the decisions in these next few days have a direct impact on the car's performance for the first few races, maybe the entire season. Because it pushes the boundaries of difficult technical decision-making, I appreciate the pressure cooker everyone is under.
For me personally, this is a wonderful time of the year, I spring out of bed early in the morning and rush to my computer to see what's happening.
