Using the wall allows you to exceed the natural grip of your tires, so you're able to carry higher speeds into the corner than without. Most tracks the speed into the corner is high enough that even light contact with the wall is enough to cause damage or cut down a tire. Martinsville is short enough that a wall ride is a viable strategy for a two corner hail mary attempt. His car was destroyed on the right side and if it werent the last lap he'd be done for. All other tracks, the corner speeds and the length of the wall are too high and long for this to be viable. You'd lose too much speed and damage the car too much

There's also a door in turn 4 for entry and exit from the track. He missed hitting it, but if he had it would've certainly destroyed the car and possibly shot him back into the racing line at almost twice the speed of everyone else. Not to mention if another car had been sent into the wall as he was coming around

This is one of maybe 3 or 4 tracks where it would even be possible. But no doubt NASCAR should prevent this in the future by dictating anything not the racing surface can't be used for a pass
