It really depends on whether you're talking about driving along a road that's had a fire front already cross it, or if you're talking about driving through a fire front itself. The former is possible. The latter is almost certain death. I've driven roads where the trees are all alight around me, embers are flying everywhere, and it's lit up in a hazy red glow all around you. It's scary as s***, but a lot of the danger by that point has passed. When a fire front sweeps through and the dry, easily computable stuff basically explodes around you through, it's pretty much as close to the fires of hell as you'll get. It's hard to find videos of firefronts hitting, because people and/or recording equipment doesn't tend to survive, but check this out:
Basically, you're screwed.
Hard to tell from YT videos whether fire front has passed, or everything around them is burning because embers came down in that area. But, yeah, see what you mean. Haven't seen video like that one, for obvious reasons. Seems like the outdoor equivalent of flashover.
