I think when they figured out they could bunch the cars up together for a more exciting race, that was the beginning of the end. I don't think anyone in NASCAR wants drivers DEAD, but if they can somehow get a lot of wrecks without people hurt, or hurt badly, that's what they're lookin for. Then, they started doing all the stupid stuff
@crackedback Rob talked about. Add all of that up and the sport isn't about actual car racing anymore. Like
@CichliDart said, NASCAR is a business. It sure as heck is. Like any big business, you get avarice and greed involved and it all goes to hell in a handbasket.
On a different note, I'd still love to see these new drivers drive some bonified 1960s stock cars. With stock based suspensions and bias ply tires. I'm not saying these newer cars are easy to drive, because Lord knows I ain't no driver, but I'd love to see these boys get behind the wheel of say one of Ned Jarrett's old early 60s Galaxies, for example.
