This week on Car Talk, Tom and Ray pondered one of rural America's great head-scratchers: How best to drive on an unpaved, washboarded dirt road? That is, those country roads that feature annoying cross-wise ruts.
Should you go very slowly, so as to follow the peaks and valleys of the washboard... or fly along atop the crests of said washboards?
Tom thought it makes sense to take it slow, even if it means getting carsick en route. Ray thought there was an ideal speed, at which one could cruise along the top of said washboard. But, of course, he had no idea what that speed might be.
You can hear their pontifications on the topic, including a discussion of Albert Einstein traveling at the speed of light, right here.
What's your theory? We want to know!
