The biggest threat to trees are burning houses. When the houses were packed like in Santa Rosa, very few trees survived:
I watched a bunch of youtube car fires. None were set by DEW. When there was no wind the car pretty much burned with wheels intact even if the tires burned. When there was a lot of wind, the downwind wheels melted. There were no videos with all four wheels melted but people didn't hang around to take a video in any wildfires. It's possible to get all wheels melted like in Greece (pic above) where cars were near each other or other special cases like where the diesel spilled out.
Wheel melting took 10-15 minutes of flame, although most fires are extinguished before that in most places with working fire departments.

You’ve done a sufficient job of making a fool of yourself on this.
If trees ‘didn’t burn’ normally, Cobb Mountain and Bottle Rock would still be dense forests. (those were subject to normal fires) or the ‘Rim’ fire in Yosemite, where they are still cutting out burned trees, and have many more to cut.
