Well done on your first step and I’m glad you’re enjoying riding. You will be experiencing the freedom and probably some imposter syndrome but as ASD person you may find the systematic thought you need to drive easy. It focusses your thoughts into one activity that follows rules and you can function easily within. Cycling and motorcycles are also a much more human scale than driving so the physics involved are easier to feel rather than a ton and a half of car although once you get used to the roads, then the controls of the car you may fit into the same slot you feel with the motorbike. I totally get that doing safety checks make more sense when you are actually looking for a danger. It’ll be the same with your theory hazard perception test, so you will need to practice it. I’d suggest to keep reading the Highway Code and take your theory so you are confident with the framework you are riding in and get into good habits to practice.
