This explanation infers a hidden variable, which is not how quantum entanglement works.

IE - it sounds like the damage occurs at the time of impact, and you just decided to look at a later point in time. But that isn’t what happens with quantum entangled particles. The particles will have opposite spin when the entangled state collapses, but measurement will affect the angle of the spin in a way that proves spin is not preselected when the particles were initially entangled and local to one another.

In your story, looking at your own car would have an observable effect on the entangled car, even though it is far away. But you also cannot even tell it was entangled with the other car without comparing the two over more traditional channels!

Edit: Since a graphic was requested, I found this image hosted by JPL, which shows a related phenomenon (quantum teleportation) to what I described, and hopefully dispels the car crash explanation which doesn’t imply “spooky action at a distance”.
