A two+ hour drive would really take it out of me. I would often have to stop and have a 10 minute nap.
I’ve found meds have really helped, I still feel tired, but I don’t have to sleep afterwards or take naps.
Same with riding motorbike, but double. I think it’s the intense concentration for long periods of time.
I’m in America and I love to push my car to its limits. I will take turns unnecessarily fast. Give me a relatively clear rural road and I will be punching that speed or greater if it’s long and straight enough. Put me on a dry dirt road and I go crazy, nothing is quite like leaving a huge plume of dust behind me.
Finding out risk taking was a symptom explained soooo much about how I drive sometimes.
Edit to add: I’ve done about 160 kph(100 mph) in west Texas on the desolate straight interstate out there. That’s kind of a limit for me in a regular car without more safety features.
