They didn't say anything about the spinning wheels AFTER it stopped.
They were talking about "rolling tire marks" that had no evidence of brakings.
The marks of rolling is different than brakings at the time of impact.
At the time of impact, if the tires we're not rolling, you would see skidding, sliding marks.
Of course after the impact, the car would stop because of the tree. After that, the air bag deployment and pyro fuse blown. No more energy could run the motor until you can replace the pyro fuse.
