I'm not a huge fan of slow tracks with lots of sharp turns one after the other. I prefer fast, flowing tracks with long straights for overtaking like Spa, RA and Silverstone. It's probably unlikely I'll ever warm to COTA unless it's in the slower cars.

Race Engineer preview
I don't know what I was expecting from the race engineer but it wasn't just a suggestion to change basic settings by one degree and test again. Maybe there's more to it than this video suggests?
I was hoping the engineer would analyse a few test laps and suggest more detailed settings, like 'you are running out of drive on the long straight, adjust your final gear ratio thus' or 'you are losing grip on corner entry, try X setting to parameter Y' with detailed explanations as to why he/she is suggesting it.
I don't know, the video makes it look a little...
generic after all the talk about a race engineer..? Still, better than nothing I suppose, and I might be wrong about the level of help offered from this short video.
