Trying to come down from the discomfort of getting home, I was up at 3 AM watching videos of how a Wankel engine works. Strange the things that are interesting in the middle of the night.
I remember when Mazda offered the Wankel for the first time. Lotta geeks I knew had to have one. A friend took me for a ride. Me: “oooh, fancy!”
