Remember my old fella telling me of his first ever pursuit fatality when he was on traffic (back in the late 70's/early 80's), some guy wouldn't stop for whatever reason when they tried to pull him and sped off (he was known to the police for violent behaviour), they followed him for about 20 minutes before he lost it trying to go around a corner too fast (my old man was doing around 70/80 behind him), he hit a tree and this before the time seat belts were widely used. He went through the windscreen and headfirst into the tree, there was nothing left of him from his shoulders up. Took my old fella a while to get over that one.
As has been said, trees and cars dont mix.
