No, I got bored standing on pit wall last time.
From everything I've seen though, none of the teams are advancing technology, just utilising what's already out.
All of the teams have pretty much been "Buy X,Y,Z, test setup, swap Y for G, test setup" rinse repeat until the cars are making the best power.
Now, I'm pretty sure that building things this way means you're basically testing what products work best in a given combination. Would you not agree?
Then if you really want to, you get an aero guy in to design stuff for your specific "box" to make it stick to the road. Now, correct me if I'm wrong, but haven't people being sticking wings and crazy aero on all sorts of vehicles for many many years?
When we're talking advancements, we're talking proper R&D, development of different types of engine, new types of gearbox etc. Have any of these teams attempted to make things like AYC, DSG boxes etc. Or are other companies making it in other areas of motor sport/competition?
