10-15 years ago, first time in DC area, I had my wife and a van full of kids. We were going around (I believe) Chevy Chase circle at 45 or so with the locals, trying to locate one of a half-dozen streets leading off it.
I was navigating and told my wife, “This one!” It was the wrong one, and we hit a speed bump hidden in the shade. I thought we had all bought the farm with broken necks and snapped vertebrae. The coolers and luggage bounced off the ceiling of the van. Good thing we didn’t have the dog with us or he would have been smashed.
When we got our senses back and pulled into a driveway to turn around, an irate local started yelling at us for speeding on his street. It was hard to ignore him but that we did.
They decided to live there. No one made them do it.
More demonstration of why I hate circles.
(Which MD - liberal that it is - has hastened to gain in as many intersections over the last 10 years as it can.)
If you were going 45 around Chevy Chase Circle, you would have deserved broken necks. You must be misremembering. It would take real speedway skillz to navigate that circle at anything over 35. The speed limit on the main through street (Connecticut Avenue) is only 25.
