1. Your safety is your responsibility.
This effectively means it’s your job to make sure you don’t get hit by other drivers. In my experience car drivers range from mildly distracted to outright brain dead, and although you’re likely to be in the right when they hit you, that’ll be little consolation when you’re in a full body cast. Which leads us to the second principle of scootin’:
2. You are fragile!
Think of yourself as a delicate butterfly in a universe of rampaging pachyderms. No matter what bike you have, you’re a tiny little speck on the road and you are very vulnerable to the elements around you. Car drivers barrel down the road surrounded by 2 tones of metal so you can imagine they have large blindspots and are overall less attentive to their environment. Always give them a wide berth and expect unsignalled turns and last minute decisions.
