The whole point of the small overlap test is to miss the crash beam and push the tire into the cabin and see how the cabin resists intrusion and deformation because it's a real life situation where there is nothing really going to stop the tire from moving into the cab because there is nothing significant in front of the tire.

I don't know what the approach is for Chevy but I think it's pretty much understood how Toyota deals with it on the Tacoma and 4Runner.

There's a cab mount behind the front wheels which years ago on Pickups and earlier 4Runner was just a cab mount. The location is slightly unfortunate when you increase wheel size so it's been common to shave and reshape it for a long time, which in Toyota circles is called a cab (or body) mount chop. No one gave much thought to it since the bracket wasn't anything special as just a way to hold up the cab.

Starting with the 2005 Tacoma (2nd gen) and 2003 4Runner (4th gen) people noticed that this cab mount grew significantly in size and gained reinforcement. It did again with the 2016 Tacoma (3rd gen), it's now massive and consists partially of high strength steel.



It's clearly designed to protect the occupants from the front suspension and wheel that is expected to get pushed back and down in an offset crash.



So there's been few forum discussions about the wisdom of continuing to do CMCs or at least to think about how you do a chop now to keep at least some of its integrity.
