Having a left hand shift motorcycle, and a right hand shift motorcycle also, it takes deliberate thought to ride them both. The brain gets conditioned to think automatically about routine actions like shifting, and braking. Neither of these bikes have a safety switch to stop me from starting them in gear, with the clutch not pulled in. The old school right hand shift bike, however, is kickstart only, so, really, you HAVE to have it in neutral, lol.
‘I guess my point is, you shouldn’t be mindless, when riding a motorcycle. There are deliberate actions that need to be performed, whenever you ride. In the 44 years that I’ve been riding, I have only left the motorcycle in gear after stopping and shutting off the engine a handful of times. If I’m parked on an incline, I try to find another level spot to park, in neutral. I always curb the bikes rear wheel, so it doesn’t move after parking, too, with the front forks turned to the left. Anytime you ride without deliberate thought, there is danger of something happening. Think about what you do, and why.
