Turbo, have a loook at this (maybe this will progress the argument):
I have used my impressive photoshop skillz once again to draw up something, that in my opinion reflects the situation and it's problems quite well. Now, bare in mind, it's not exact science. I didn't draw these illustrations with accurate measurements. They may be inaccurate to a point, but I think they should be taken into account.
First of all, I came across this:
I have no idea how accurate it is, but assuming it is, it gives you a fair idea of what a human is able to see in his peripheral vision. But
, I must stress that this does not necessarily apply to an F1 driver or any person wearing a full enclosed helmet and in the case of an F1 driver, has also rather restricted movement as a result of HANS and the enclosed area. I have raced my car (Lotus Exige) on the track, with a helmet and I know first hand that there is a huge difference in perception when wearing a helmet. My car has racing harness and that also restricts movement quite a bit (I'm literally strapped to my seat, so movement is restricted to the head).
There are various studies how wearing helmets restricts perception on what is going around you. I came across this study in my quest to figure out if there are actually numbers of actual FOV when wearing helmets. It's a PDF document, which I shall link here: https://www.google.com/url?sa=t&rct=j&q ... 9mTUnZrY2l
Bear in mind, this document goes further than just exploring the limits of FOV when wearing helmets, but also takes into account that motorcyclists have quite a bit of freedom in head movement. This obviously does not apply to F1 drivers strapped into their seat.
Anyway, moving on. Here is what happened on track. I didn't count the frames, but the frames cover approximately 2 seconds between the point when Vettel moves to the inside and the point of collision. Unfortunately, we can't really see how far up Sebs front wing is relative to Max, but we do know that at the point of impact, Seb's front tire was behind Max's front tire:
Now to my illustration: I took the Ferrari from-above-shot to illustrate the respective drivers position and their vision as well as what they are likely to see through their side mirrors. It's just an approximation. Bear in mind that the drivers FOV is very likely less than what I drew up because they are wearing a helmet and restricted movement. The side mirrors are also very limited too. They are not pointing outwards, but towards the back so that drivers see what is happening behind them, not to the side of them.
I have two positions. Seb decently up alongside and the position he was at his farthest, at the point of impact. As you can see, even when Seb is decently up alongside (front wing level with drivers position), due to the limited FOV, it is still quite unlikely that the driver will actually see him. Look at the first picture and take into account FOV in the vertical plane and imagine how tucked in a driver is into the car and the restriction the helmet imposes. Would he see the front wing? Also bear in mind, again, how quickly Seb went from behind Max to the inside and to point of impact (< 2 seconds). I actually tried to measure it on my phone and my conclusion is around ~1.5 seconds between the moment Vettel darts for the inside and the point of collision.
Come up with your own conclusions:
Now, again, I ask - to what point is Max Verstappen responsible to see all that what unfolds within <2 seconds and react to it?
Also, bear in mind that the racing line is the line with the most grip. Anything beyond the racing line offers less grip (less rubber). Verstappen was on the ideal line, with the most grip that offers the highest apex speed. At the point of turning in (Seb probably not in his FOV) he was committed to the corner at the speed he was doing and his turning angle. If he releases his steering lock at that point to go wide, he will not make the corner at the speed he is doing as his momentum will carry him out. Also moving beyond the racing line means less grip. Decelerating at that point means the balance of the car shifts, with potential oversteer, especially if you factor in if this happens beyond the racing line.
I'd be quite interested to hear your thoughts while considering all these points.
