I paused the video and thought about it for a few minutes. I suck at this type of math so I was trying to solve it without using any numbers.
When you are performing a emergency stop you feel the force on your body, the force that cuts the seatbelt into you, increase gradually. This means the rate of deceleration increases over time. This means most of the deceleration happens in the end. Which means the red driver is fucked. I guesstimated, without calculations, it would be between 50 and 70, so I was still surprised.
Of course it also helped that he told us the answer was surprising, I wouldn’t have thought about it as long otherwise.
