They can race road courses. NASCAR has just gotten too lazy about punishing dumbass driving behavior. Every other series in the world penalizes drivers for reckless passing. NASCAR use to do it some with black flag. They don't bother anymore. Now any time there's a road course, you're seeing guys go 3 on up to 5 wide into a turn where there's no fucking chance to complete a clean pass yet there's no penalty. Drop a couple black flags and most of that stuff would get cleaned up real quick
"3 up to 5 wide"??!?
Brah, at Indy this weekend they would fan out 8 wide at the peak of their idiocy going toward turn 1, and all of them knew it didn't have a prayer of working and that they wouldn't all make it out of turn 1 with the nose of their car pointing in the right direction. Did they care? Nope. That's a combination of amateur level impatience, entitlement, lack of road course racing IQ, and just general dickface idiocy. Plus, of course, the knowledge that these cars really aren't built for these road course tracks so there's very minimal passing zone or opportunity. It's just stupid and it doesn't work.
I get it. Some "fans" watch for the demolition derby. They more wrecks, the better. The more drama, the better. I don't watch any racing series for the wreck fests or the drama. It pisses me off, generally. I watch because I love the competition, the skill, the cars, the engineering, and the talent it takes to make these cars go THAT fast, that close to each other, with regular incidental racing contact, etc. Often, the aforementioned is on display and there's a really good racing product on my screen. But the vast majority of these road courses are not that. It's a bunch of poorly trained kamikaze pilots out there going "full send" into situations they KNOW they or someone else won't make it out of. Perfect example is Kyle Larson. There are many many people out there who regard him as the bester on the circuit, and maybe in America. Welp, Kyle Larson is no fkn road course racer, and that was on full display as he decided to go full yeet and go into [turn 1 I think it was] about 30 MPH faster than would have ever worked. The result was two obliterated race cars, and he could have really seriously injured himself or the other driver. It was bush league, dangerous, and embarrassing. This is the NASCAR reigning Champion who completely and entirely ran out of talent and made a conscious decision to "video game mode" a turn.
I'll even take the time right now to list the current, active NASCAR Cup Series drivers who actually have chops and credibility enough to be called at least "decent" road course racers:
Chase Elliott
Kyle Busch
Kevin Harvick
Kurt Busch
Austin Cindric
Ryan Blaney
Martin Truex
Joey Logano (ehhh, but I'm trying here)
Tyler Reddick (iffy, but he showed me something Sunday)
AJ Allmendinger (i'm being generous now because he's not a Cup full timer)
That's 10 drivers. A fkn generous 10. Yet they roll out a starting grid of 38 cars. So 28 drivers who haven't a dagblasted clue how to turn left and navigate the nuance of road course racing are out there dive bombing, fanning out 8 wide, and just looking like absolute fools out there.
This outrageously long winded post is to articulate my point that NASCAR should be doing road course racing LESS, not MORE, and that across the board, the combination of NASCAR drivers and cars are not built for this style of racing, and they're stinking up the show. NASCAR was, and still is, a racing series that is built for ovals. If I want to watch GT3 style road course racing, IMSA does it better, and so does various other series, mostly foreign. I'd even watch F1 or Indy for that road course style fix before I'd advocate for NASCAR to do it more.
There should be 3, MAYBE 4 (TOPS) road course races on the NASCAR schedule. Sure, rotate amongst COTA and the super speedway infields (in addition to the staple Sonoma and Watkins Glen) for some flavor and variety on a year to year basis. Maybe run the standard Brickyard Oval one year, the infield the next, etc (rinse and repeat for Daytona infield...rotate every other year). But to roll out a schedule with 6-8 road course races in a single season featuring cars that weren't engineered to do it and a field of drivers uninterested in actually learning how to do it professionally, that's ridiculously stupid and I'm clearly over it.
