Kyle Busch races alongside Carson Hocevar and Chris Buescher during the NASCAR Cup Series Würth 400 at Texas Motor Speedway on May 3, 2026.

Kyle Busch isn’t backing down after one of the most debated moments from Texas Motor Speedway.

Following a late-race clash with John Hunter Nemechek, Busch took to social media with a blunt defense — and data to back it up.

“I did not start this,” Busch wrote. “The 42 apparently doesn’t know where the RS of his car is and where he is in relation to the outside wall.”

The post, which included SMT telemetry and in-car footage, quickly fueled debate across the NASCAR world after a chaotic sequence that left both drivers with damaged cars and disappointing finishes.

Late Restart Turns Into Flashpoint

The incident came in the closing laps after a restart shuffled the field.

Busch, who had spent much of the day running inside the top 10, was fighting to regain track position when he got back alongside Nemechek’s No. 42 entering Turns 1 and 2.

The two raced tightly side-by-side — and that’s when things escalated.

There was initial contact on corner exit, with Busch getting squeezed toward the outside lane. His No. 8 Chevrolet drifted up and slapped the wall, taking visible damage.

Moments later, the situation worsened.

Busch veered right as the cars continued down the straight, making further contact that sent Nemechek into the outside wall as well — the moment that has drawn the most scrutiny.

Two Completely Different Stories

From there, the narratives split.

Nemechek made his stance clear almost immediately.

“Not freaking clear,” he posted. “Great day going, and just got wrecked. What an ass.”

Busch responded not just with words — but with data.

In his post, he shared SMT telemetry showing steering and positioning inputs, arguing that Nemechek drifted down the track and misjudged the space available.

“There was 2 ft outside him and I was judging my left side tires to the hash marks,” Busch wrote. “Always know who you’re racing beside.”

The Detail That Matters Most

One key detail stands out when reviewing the sequence.

Before the initial contact, Nemechek does not appear to be fully pinned against the outside wall — there is space, but it’s shrinking as both cars move through the corner.

That makes the first contact debatable — a tight racing situation where neither driver gives much.

The second move, however, is where the conversation shifts.

Busch’s move to the right after hitting the wall is what sent Nemechek hard into the outside barrier — and depending on interpretation, that’s either loss of control or retaliation.

How It Impacted Their Finishes

What’s not up for debate is the outcome.

Both drivers saw strong days fall apart in seconds.

• Kyle Busch finished 20th after limping his damaged No. 8 Chevrolet to the checkered flag
• John Hunter Nemechek finished 21st after being forced down pit road following the contact

For two drivers who had shown top-10 speed earlier in the race, it was a costly ending.

Why This One Is Sticking

This wasn’t just another mid-pack incident.

It had everything:

• late-race pressure
• visible contact and damage
• a second, more controversial hit
• and now, data-backed finger-pointing from one side

Busch going public with SMT data adds a different layer — turning what would normally be a “he said, he said” into a deeper debate about positioning, awareness, and intent.

And as usual in NASCAR, the truth depends on who you ask.
