Fair enough. I may have worded it poorly the first time but we got there.
As for what a driver feels in a cup or F1 car while cornering, I get that lateral Gs are felt. But, I always felt like it was mostly just a result of centrifugal force. Basically just the result of the changing direction. Regardless of the physics involved they have been using padding to combat those forces in an effort to make the cars easier to drive under those loads.
The fastest I ever ran in a roundy round car was @170 mph up at Chicagoland speedway. To be honest about it, I can't recall really noticing the forces involved while cornering due to the headrests, shoulder rests, side bolsters on the seat holding me in place. Now, I would imagine by comparison the seat construction of the 80s with just an aluminum rib support and head support with very minimal cushion would have felt much different. But again it has been some time sine I did anything in a roundy round car and I only hot lapped the car at Chicagoland so wasn't like I had to endure it more than just a few laps.

Over the winter, social media was awash with pictures and videos of drivers pushing their bodies to the limits in a bid to prepare for the increased physical challenge presented by 2017’s new breed of F1 car. And when you see the G-forces Lewis Hamilton is subjected to in the video above, you start to understand why the drivers were forced to adapt their training regimes.
As you can see, in almost every one of Albert Park’s corners and braking zones, polesitter Hamilton - en route to the fastest ever lap around the Australian circuit - is subjected to forces well in excess of those seen in 2016, such is the improved cornering and braking performance of his Mercedes W08 over its predecessor.
Unsurprisingly the biggest G-force differences from this year to last were seen in Albert Park’s quickest corners, with the drivers now pulling over 6G through Turns 1 and 11. In the latter of these bends, the forces acting on Hamilton peak at 6.5G - 0.2G more than the most extreme rollercoaster on the planet delivers.
Over the course of 57 laps, that’s a lot of extra G-force for the drivers to cope with. And it’s worth noting that the weather in Australia wasn't particularly warm, nor is Albert Park one of the most demanding tracks…
Info I'm finding on NASCAR is 3 to 5 G's depending on the track, but they need to withstand them for more than twice as long. No F1 race is allowed to go over 2 hours
