Yes it would be choreographed just to see at what speed it would be possible at or if in fact constant overlap is even possible with the speed adjustments you would have to make, proving that is what I thought the whole debate was about, whether it is possible at race pace to go side by side at every corner that is 2 cars wide. If we can do it even choreographed at DT chicane then should be possible pretty much anywhere.
It's safe to say that you would never see it done in an actual race as pretty much everyone who has the skill to do it would realise it's not exactly the best move in any situation. All it would do is risk a massive crash, lose both drivers time and not settle the position just delaying the fight to the next corner which would happen anyway if one driver backed off. But I can always show you the choreographed move anyway (assuming it's possible actually being side by side without someone pulling ahead) as I'm sure it would be fun to watch.
