You are 100% right. It doesn't make sense, what he said. I just think that what he was thinking didn't come out right it words. His overall point was that having this strange nose is going to cause instability...and I do agree with that. Maybe not a lot. And maybe the drivers will get used to it. But I do believe this instability will exist.

No it's not different. I've never heard the term flow angles. All cornering work is done solely on the rate of turning compared to the speed of the car, hence the term "yaw" used in the aeronatical industry. And The longer the car the more noticeable the yaw effects.
Side winds are a different matter than cornering and are a simpler analysis, however the symmetry of the car could matter more here.
For Sure!!

It will cause as much instability as having a camera pod on the right side of the engine cover and none on the left. It's not a big deal.
For Sure!!

Disagree if you'd like as we are all entitled to our own opinions. But as he has decades of F1 experience over multiple teams, I'd give him the benefit of the doubt. It is possible that he misspoke or since English isn't his native language, maybe he chose the wrong word.
I believe he said this to an Italian F1 news site. Then someone translated it into English so perhaps there is something not translated properly.

I don't know if I agree with him myself only thing that comes to my mind is the comparison of the FW26 which nose clearly didn't work. And nobody gives a good reason as to why it didn't.

Well considering this:

I believe whatever effect it has on stability will be negligible, until somebody articulates a clear and sensible argument otherwise.

Why not? That's exactly the trap - thinking anyone is infallible and that everything they say is either (a) true or (b) true all the time. Doesn't matter what their name is. Not one bit.

Indeed. For example, you might think orange sherbet is the best type of ice cream. I would disagree and judge chocolate chip cookie dough to be superior. Opinions are one thing, engineering is another. Some of the things I've seen in these videos and articles just aren't correct - some spoken and some written / illustrated. Not calling the guy a bum, just calling it how it is in these examples.

Now back to opinions - IMO one of the most important things as an engineer (especially in motorsports) is to be as far and objective as possible. Everything you hear or read or see - have to strip away who said it and just see if it adds up or not. Doesn't matter if it came from a F1 or F3 guy, 3 decades experience or 3 years experience. Having the confidence to throw "established" stuff out is how you get ahead sometimes.
Grip is a four letter word. All opinions are my own and not those of current or previous employers.

and that's flow angle
