More drama during my recent visit to New Jersey Motorsports Park. I was following a Corvette at Lightning coming around turn 3, when he started to put out a little puff of smoke from the rear. Then his engine just let go. I was caught in a cloud of grey-white smoke for what seemed like an eternity at the time. I couldn't see squat, and just hoped he drove it off to the outside as I braked and went to the inside. Luckily I guessed correctly.
Sorry to see it happen to the guy, but sure happy I didn't hit him and make things even worse.
