1688 Roundabound

So I was driving through a roundabout the other day and thinking, there sure are a lot of them these days. You might even say roundabouts roundabound. Like someone made it worth someone else's while.
I actually like roundabouts. For the most part they're way faster than waiting at stoplights. And I really hate waiting at stoplights.
If I'm going from my house to the grocery store I use, I can go two ways. One involves two lights and five roundabouts. The other involves seven lights. Roundabouts beat it every time.
But it's not just the speed, or the good feeling that comes from continuous motion and progress, however slow. No, it’s the challenge factor. The miniature adrenalin rush that comes from knowing the other folks in the roundabout with you may screw up. The potential crash factor. It adds an element of danger.
Suddenly you're not just driving to the store, you're in a potential demolition derby, or a NASCAR race.
And that got me thinking. We've basically glorified a "California Stop" here. The drifting through an intersection that puts a lower premium on the stop factor of a red light when no one's obviously coming. We've institutionalized that mentality with a roundabout, where the situation remains fluid and filled with judgment and not arbitrary authority.
All good, but what about the wear and tear on our suspension and tires? All roundabouts are left-turning. Oh sure, you have to turn right to get on and off, but the bulk of the roundabout is a left-turning circle. Go fast—turn left. It's NASCAR in miniature.
So are car repair places profiting more from the NASCAR effect on tires and tie-rods? Was lobbying involved in their sudden popularity? Are roundabouts just a roundabout way of getting new profits for repair shops?
Or is this just an example of my bad circular reasoning?
America, ya gotta love it.
