I used to be exactly like you. I drove mid-price cars (around 10k) and was 100% miserable. I could drive shorter distances around town, but I was completely worn out after 200-300km of continuous driving. When we got wherever we were going, I needed to take a good 30-45 minutes to rest my brain.

I bought a Hyundai EV about a year ago and I actually kinda like driving now. The electric drive train is somehow more logical to my brain. I tell it to go faster and it does without any fuss or noise. No switching gears manually or alternating engine RPMs from the automatic gearbox.

The best part is the lane keeping assistant and smart cruise. When I'm on a bigger road with proper markings, I can just lightly hold the wheel and the car does the annoying minutiae of driving.

Now I can easily drive 400km+ in a single day and not feel completely drained afterwards.

Something about the need to slightly manage the steering wheel every second while also maintaining a safe distance to the car in front of me drained my brain. I was unable relax at the wheel. Now I can focus on actually following the traffic around me.
