The car of tomorrow was smoking at Martinsville. It was a caution-fest. I stretched out on the only cot I know. It was easily a two-napper. Harvick and Kenseth were among some racers that were breathing some nice melting foam vapors. Mmm, that has to be healthy. Oh but no, Nascar assured all that it was non toxic. Riiight. We'll take there word for it. Meanwhile the announcer is confirming that it's impossible for the foam to catch fire. It's not possible. No siree. Melting, burning, whatever you want to call it. Either way, many racers were walking around staggering, reaching for the headache medication. They'll figure it out eventually, the car has only been in the works for 7+ years.
