You’re failing the shibboleths though. You don’t drive a motorcycle, you ride one. A 500cc bike is low mid range, not a beast. You can’t hear rolling or engine noise of cars, trucks or busses over 50kph if you’re wearing a helmet.

Further, sound deadened cars with the stereo on an appreciable level also aren’t conducive to perceiving what’s around you.

Speaking as someone who commuted on 600 twins and 300 singles for years, if you’re wearing hearing protection and listening to some tunes and navigation hints you’re fine. Just ride defensively like you should, and make sure you’re not over doing it on the volume.
