The Trackhouse Racing team didn’t exactly have the best showing during Sunday’s NASCAR Cup Series race in St. Louis. But things could stand to get even worse for the team after some bizarre post-race behavior from drivers Ross Chastain and Shane Van Gisbergen.
Chastain and Van Gisbergen, both of whom are currently in the series playoffs, finished 24th and 25th, respectively, in the race. Meanwhile, teammate Daniel Suarez, who is not in the playoffs, finished 35th after an early crash.
The finishes left Chastain just 19 points above the playoff cut line, and Van Gisbergen 15 below, with one race remaining in the current round of the playoffs.
But the team could face additional scrutiny after Hendrick Motorsports driver Alex Bowman pointed out some erratic driving by the two after the checkered flag had flown.
Trackhouse Drivers Oddly Drive Through Grass After NASCAR Race At St. Louis
Following the final lap of the race, Bowman and the rest of the field were coming back to pit lane when the driver of the No. 48 Hendrick Motorsports car pointed out that Chastain and Van Gisbergen were driving strangely.
“Hey, the Trackhouse cars are driving through the grass. That’s kinda cool,” he said sarcastically.
Sure enough, video of the cool-down lap shows both Chastain and Van Gisbergen intentionally swerving their cars into the grass multiple times before pulling into pit lane.

It’s not uncommon for NASCAR drivers to swerve on the track after the race. All cars have a minimum weight they must meet after the race, and by swerving, cars can often pick up discarded rubber from worn tires and add to their weight.
But swerving through the grass is one that hasn’t really been seen before, raising suspicions as to why the drivers may have been advised to do so.
“This seriously needs to be investigated but since they’re not Hendrick or Gibbs cars, nothing will happen,” one fan posted on X.
“This is definitely suspicious,” said another. “Damaging the diffuser so that it passes post-race? Or maybe gaining weight? Those are two suggestions I saw in the comments. That’s a good guess to start…”
Ultimately, NASCAR will probably look the other way on this. It’s not the first, nor the last time that drivers behaved bizarrely after the race. And it’s not like it helped Trackhouse all that much, given their finishes.
But it’s certainly one of the weirder things you’ll ever see after a race.
