I have some family members that are huge fans, so I follow somewhat. It should be noted with your link that Darlington is a much faster and lengthier track than Martinsville. At Darlington, Larson was very close to Hamlin when he initiated the wall ride halfway through the corner - he may have gained a half second or so, not several, like at Martinsville. I see this as more of a Richmond/Martinsville short track strategy. So now that we know it's possible at Martinsville, it'll be great to see what happens next time they visit or on the next short track race.

I personally don't see this happening a lot. I raced motorcycles at the professional level for several years. If someone had continued doing something that gave them a 3 to 5 second advantage on the last lap, the rest of the paddock would have gotten tired of it pretty quickly. Although I think it's a hilarious situation, I would imagine if it continues to happen that the drivers doing it will start to feel pressure from the other drivers.

If it gets to where this is happening all the time, I don't see the series not making a rule against it, but they are probably gladly accepting the needed publicity at this point.
