Here we go again...so once more, I'll chime in. I have crewed in IMSA, SCCA and NASCAR, so I have a little experience here. First, if you think NASCAR isn't hard, then get off your butt and go do it. It is extremely tough and makes an event like like a typical Grand Am race feel like a spring picnic.
And while it seems like they are not very advanced, try really looking underneath one and then find out how much time they spend on shaker rigs (yeah, just like F!) and in wind tunnels. And then lets talk about setting up a car on an oval. You adjust each corner individually, not front to rear like a road race car, and there are numerous adjustments to each corner. Then let's throw in how much each corner will change during the race, and how you have to adjust each one during a 14 second pit stop. The driver being able to explain how the car works is paramount. If your driver cannot communicate and work with the crew chief, your car will be junk.
And while the car is about 98% at tracks like Daytona, the race itself is anything but easy. Your grandmother could qualify the car, but she couldn't make the first corner in a race. Once you get all 43 cars out there, it's a different story completely. Imagine driving on the windiest day you can think of with the car blowing all around, and them multiply it by a hundred. Then imagine you are doing 200mph at the same time with all your buddy's banging into you. Oh, and the car turns left really well, but right, not so much. It's why when Kyle Busch saves his car like that, it really is a big deal.
We were a road racing team fresh off a championship, and I can assure you, these are highly skilled people and it is real racing. It's very different from road racing, but no less demanding. In fact, it takes a ball size (sorry Danica ) much greater to run an oval than a road course, and a vastly different skill set. There are very few drivers from other disiplines that can jump into a NASCAR and win right away, no matter what team they drive for.
The OP is 100% wrong on every topic he listed. And while NASCAR is not my favorite racing series to watch or drive in, it is complete wrong to say it is without skill or that is not real racing. And though I think Kyle Busch is the biggest putz in racing, I think you could drop him into an Indycar, or even a Red Bull and he would run at the front and win.
