cool old vid of 50s cars

Gosh, you'd think with all those horrible gross polluters, there'd be grease, oil, smoke and crap all over the road. Amazing, ain't it?
Yeah, you're right! I didn't pick up on that. I remember in the late 60's, on some roads there would be an oil/grease stripe down most lanes, as thick as 3/8". It was treacherous on a motorcycle.
