A bad day at the race track many years ago

Does the freeway count? I was driving my work truck (Isuzu NPR stakebed) back in 1994-ish and I passed a newer (at the time) convertible Bentley with smoke coming out the engine cowl. I pulled over, got out and tossed him my fire extinguisher. As soon as he opened the hood, the fire blew up and he started blowing the thing down from the top and quickly ran the extinguisher out before he even hit the motor. No one else stopped and we watched this car burn for 10 minutes before the fire dept made it down the jammed up freeway. He was a late 20's arab looking guy and I'm not sure the car was his or his dads, but it was gone before they had a chance to put it out.
