Agreed, the loaner P85D he was driving in that video did not have Ludicrous mode, it was just "Insane". And judging by his reaction, he felt that term was spot on. [emoji6]
It's interesting how some people react physiologically to the rapid acceleration in Insane mode. They can get blurred vision, dizziness, nausea; none of which you want to experience while driving. I test drove a P85D in Insane mode early this year and happily did not have those reactions under max acceleration. But apparently many people do.
My inner ear is very messed up, I can't fly without dramamine under any conditions. One thing that can trigger motion sickness in those prone to it is a sensory disconnect. I know people who have become ill in IMAX theaters because of the brain's confusion between what the eye is taking in and what the inner ear feels. From the review in Consumer Reports, the guy who test drove the P85D the first time in Insane mode said it was the most terrifying thing he'd ever done in a car and he's driven some of the highest performance sports cars in the world. He said what made it so terrifying was the disconnect between the acceleration and what you heard. With ICE sports cars that can pull big gs, you have the audio sensation of the engine screaming, but the P85D is quiet and that can scramble the brain used to the noise.
Compared to what someone would experience in a fighter, the 1 g the P85D can produce is not that much. A WW II dive bomber would usually pull out of a dive at around 5gs. WW II fighters could do 7 and modern fighter pilots need to be rated to 9gs. The planes can often do more than that. A USN catapult launch is about 2.5gs.
But all these things are done in environments where there is a lot of experience and in many cases you have a lot of room to do something if something goes wrong. Even launching from a carrier you are well away from the ship by the time you know there is a problem and there is always a rescue helicopter in the air if you need to punch out. With a car accelerating that hard, unless you're on a test track, there is the added risk that if something ends up in front of you, things are going to go pear shaped very quickly combined with the silence. Because of the silence, people who might step out into the road, or an animal, or another car can't hear the noise and know someone is hot rodding.
