They did the math and the impact of the accident with Stroll the past week was at the force of 50G.
This is impressive, I'm not sure that a normal human (not f1 athlete with huge neck muscles) can survive at it.
A few weeks ago I saw a video they made to "test" the ability of normal people to deal with the force of gravity on their heads and then comparing it to another video of an F1 driver... it's an absurd difference.
I believe that a "normal" person would certainly come away with some serious consequences from this accident.
Regarding the accident, Stroll compared its impact to the same one he suffered at the Mugello circuit during the 2020 campaign, saying that both had a very similar intensity.
I believe that Stroll took the right action in not racing at the Singapore circuit... unfortunately Aston Martin as a whole is not doing very well either, with Fernando Alonso finishing in last place after a series of incidents he had.
Who knows, maybe things will get better in Japan!?
