Last time this was brought up somebody pointed out that in certain countries (Germany, I believe) it is actually illegal to drive without purpose, so endlessly circling the roundabout would be illegal. I’m so confused how this could ever be enforced though, not the roundabout thing, but generally. Not anymore, but during lockdown I would put on an audio book and just drive around the countryside for hours. The purpose was keeping me sane, but I wasn’t going anywhere.
