It shouldn't have worked. Physics says that when a two-ton stock car slams into a concrete barrier at 130 miles per hour, the result is usually a pile of scrap metal and a yellow flag. But on a humid October afternoon at Martinsville Speedway in 2022, Ross Chastain decided that the laws of motion were more like suggestions. He shifted into fifth gear—a gear you never use at Martinsville—floored the throttle, and let the outside wall steer his Chevrolet Camaro through turns three and four.
The "Hail Melon."
If you’re a racing fan, you’ve seen the clip a thousand times. If you aren't, you probably still saw it on SportsCenter or TikTok. It was the NASCAR ride the wall move heard 'round the world. Chastain needed to gain two spots on the final lap to make the Championship 4. He gained five. He set the fastest lap in the history of the track—by nearly two seconds. It was a video game glitch brought to life in the physical world, and it fundamentally changed how NASCAR looks at safety and sportsmanship.
The Science of the Wall Ride
Most people think Chastain just got lucky. He didn't. He knew exactly what he was doing, even if he wasn't sure he’d come out the other side with four inflated tires. By intentionally grinding the right side of the car against the SAFER barrier, he used the wall as a guide. This allowed him to maintain a centrifugal force that would have otherwise sent him spinning into the infield if he tried to turn that sharply at that speed.
Basically, the wall acted as a massive steering rack.
Normally, a driver has to brake heavily into the corner to keep the tires from sliding. Friction is the enemy here. But by leaning on the wall, Chastain eliminated the need for tire grip. The wall held him in place. It’s a trick kids have used in NASCAR 2005: Chase for the Cup on the GameCube for decades. Doing it in real life, however, requires a specific set of circumstances. You need a short track. You need a composite body that won't crumple like a soda can. And you need a driver who is willing to risk a massive concussion for a shot at a trophy.
Why the Next Gen Car Made it Possible
We have to talk about the car. Before 2022, NASCAR used the "Gen 6" car. Those bodies were made of sheet metal. If you touched the wall with a Gen 6 car, the metal would bend, rub against the tire, and cause a blowout within seconds. You couldn't "ride the wall" because the car would effectively eat itself.

Then came the Next Gen car.
NASCAR moved to carbon-fiber reinforced plastic (composite) body panels. These things are incredibly durable. They pop back into shape. When Chastain hit the wall at Martinsville, the panels vibrated and sparked, but they didn't collapse into the wheel wells. This technological shift was the only reason the move worked. Without the Next Gen’s durability, Chastain’s car would have been a heap of junk by the time he hit the start-finish line.
The Safety Controversy and the "Chastain Rule"
The reaction was immediate and polarized. Fans loved it. It was the kind of "check this out" moment that NASCAR desperately needs to stay relevant in a crowded sports landscape. But the drivers? They were terrified.
Kyle Larson, who had actually tried a much smaller version of this move at Darlington a year prior, called it "embarrassing" for the sport. Joey Logano pointed out the obvious: if this is allowed, what stops every driver from doing it on every final lap? The safety implications were a nightmare. The SAFER barrier is designed to absorb impacts, not act as a high-speed rail. If a piece of Chastain’s suspension had snapped and sent the car over the wall or into a gate, we’d be having a very different conversation today.
NASCAR’s Official Stance
NASCAR officials didn't penalize Chastain that day. There wasn't a rule against it. But they knew they couldn't let it happen again. In early 2023, the sanctioning body issued a formal ban on the NASCAR ride the wall maneuver.
They didn't actually write a new law in the rulebook. Instead, they pointed to Rule 10.4.4.B, which covers "Safety and Integrity of the Event." Essentially, NASCAR declared that any move that compromises the safety of the driver, officials, or fans—specifically referencing the wall ride—would result in a time penalty. If Ross tried the Hail Melon today, he’d be moved to the back of the pack, and his heroic dash would mean absolutely nothing.

Famous Attempts (and Failures) Before the Ban
Chastain wasn't the first person to think of this. He was just the first person to do it perfectly.
- Kyle Larson (Darlington, 2021): Larson tried to wall-ride the final turn to beat Denny Hamlin. He slammed the wall, but he didn't have enough momentum, and Hamlin still beat him.
- Carl Edwards (Kansas, 2008): In a desperate move to pass Jimmie Johnson, Edwards sent his car into turn four way too fast, hoping the wall would catch him. He actually hit the wall and crossed the line first, but the impact slowed him down so much that he didn't technically "ride" it—he just bounced off it.
- Various iRacing Exploits: Before it happened in real life, the "wall ride" was a known exploit in the iRacing simulation. Professional drivers who use the sim had seen it work in the digital world for years.
It’s kinda funny how the virtual world predicted the most viral moment in modern racing history.
The Fallout: How the Sport Changed
The "Hail Melon" changed Ross Chastain’s career. Before that move, he was seen as a talented but aggressive "interloper" who ruffled too many feathers. After the move, he became a household name. Watermelon sales probably spiked (Ross is an 8th-generation watermelon farmer, if you didn't know).
But it also forced NASCAR to tighten their grip on "unconventional" driving. The sport has always had a "if it ain't in the rulebook, it's legal" mentality. Chastain broke that. Now, there's a hovering cloud of "discretionary penalties" that makes drivers think twice before trying something truly insane.
What This Means for Future Races
If you go to a race at Bristol, Martinsville, or Richmond today, don't expect to see anyone pulling a Chastain. The penalty is too stiff. However, the move has sparked a broader debate about track limits. In Formula 1, track limits are a constant headache with white lines and sensors. NASCAR has always been a bit more "wild west."
The NASCAR ride the wall ban is the first step toward a more regulated version of the sport. Some fans hate it. They think the "send it" mentality is what makes stock car racing great. Others are relieved that we won't see a car go airborne because someone tried to be a hero in turn four.

Honestly, it’s probably for the best. The sheer force Chastain felt inside that car was massive. He described it as a "blur" and said his vision went wonky for a second. We got our legendary moment, we got the die-cast cars, and we got the highlight reel. Now, let’s keep the cars on the actual asphalt.
Lessons from the Hail Melon
What can we actually learn from this? It’s more than just a cool trick.
- Preparation meets opportunity. Chastain had thought about this move since he was eight years old playing NASCAR 2005 on the Nintendo GameCube. He didn't just wing it; he had a "what if" plan in his head for twenty years.
- Technology dictates strategy. The move was impossible five years ago. It will likely be impossible five years from now if car designs change again. Always understand the limits of your equipment.
- The "Safety" Trump Card. In any regulated environment—whether it's sports or business—safety will always be the ultimate regulator. If you find a "glitch" that is dangerous, expect it to be patched immediately.
If you’re watching a short-track race this season, keep an eye on the high line. Drivers still get as close to that wall as possible to find speed, but the days of using it as a literal rail are over.
How to Follow Modern NASCAR Strategy
To see how drivers are finding speed now that the wall ride is banned, you should pay attention to:
- Tire Fall-off: Watch how much slower the cars get after 30 laps. This is where the real racing happens now.
- The "Diamond" Line: Instead of riding the wall, drivers will enter high, dive low in the middle of the turn, and exit high. It’s the fastest way around most short tracks without breaking the rules.
- Brake Bias Adjustments: Listen to the scanner audio. Drivers are constantly tweaking their brakes to help the car turn without needing a concrete assist.
Chastain’s move was a once-in-a-lifetime event. It was the perfect storm of a desperate driver, a durable car, and a specific track layout. We’re lucky we got to see it, and we're probably lucky it's now illegal.
Next Steps for Fans:
To truly understand why the move was so fast, you should look up the lap telemetry from the 2022 Xfinity 500. Compare Chastain’s throttle input on the final lap to his previous 499 laps. You'll see that he never lifted. It is the only lap in the history of Martinsville where a driver remained at 100% throttle through the entire corner.
