Scooters and people will always be an ongoing battle with each other - lol.
All are right part of the time, and all are wrong part of the time. That's because there will always be inconsiderate people on both sides as that is human nature. We will not change the human race.
For the most part when I get irritated - and yes, I 'do' get irritated often at how insensitive and rude people can be - I just let it go and move on. I don't have time while there to waste thinking on bad behavior.
I'm just glad I don't have to 'be' that person, or live with them. They can't be happy.
