I'll chime in with my routine:
I practice bailing from the car in a pitch black garage. I do this while holding my breath.
My default set up for the Datsun is bail out the passenger side as you don't have to lower the window net and it's 2 seconds faster than bailing out the drivers side. The F500 has one exit. I condense all the movements as much as possible as I've found this cuts 1.5 to 2 seconds.
BUT that may not be possible; I also practice the things I'll do if the car is one it's side (left or right) as well as upside down.
NEXT
I have the car is on fire check list; step one and two are fuel pump off pull the fire bottle (I'm transitioning to automatics). Note I have race cars with carbs so I could drive 1/4 mile to a turn station if I wanted to.
Notice driving to a turn station is not a priority; if the fire is anything but minor I'm bailing..........screw the car let it burn to the ground. Burns are some of the worst injuries one could ever imagine just ask anyone who's been in a burn unit.
DId I mention screw the car?
NEXT
If you have the gear wear the gear; I wear every scrap of gear becuase you never know. Also unless you have a compelling reason not to, get a full face helmet (I'll get back to this)
NEXT - you never know.
My fire was in our sports racer; we had the track to ourselves for a private test day. In retrospect this was really really stupid; no course workers, no ambulance, nothing, this could have been really bad.
Going into Spring Mtns fastest corner (about 130 mph) the Yamaha 1000 engine shat itself. The oil atomized and then ignited. The car had a bit of ground effects so I got to see the flame travel up the sidepod and then pour out the front fender. Fortunately I'd practices turning everything off while driving as well as doing a dummy run pulling by the fire bottle. The oil had also lubed the rear tires so I was also catching a 130mph slide whole doing all this. Practice helped a lot.
The fire lasted all of 3 seconds; I've had way scary moments racing motorcycles bit I wouldn't want to repeat it.
Finally a put a decade ago a friend's Vette burned to the ground; from the time it caught fire (the car being him saw it) to the time it was fully engulfed was 20 seconds. He was wearing an open face helmet and when he open the door the fire burnt the tip of his nose as well as his left check. Fortunately they were minor burns. He immediately bailed out the passenger side. In the 2 seconds it took to leap out the passenger flames were rolling over the door sill.
Note: Yes I'm trying to scare you; becuase the only thing you should be grilling trackside is burgers and hot dogs.
