Lawlessness on the streets

As a cyclist, I really hate it when I have to ride into the suburbs on arterial roads. The speed limit is posted at 50Km/hr and they are all driving 80. They are speeding by so close, almost clipping me. It’s twilight and I worry if they can see me or if they are even looking at the road instead of their phone. To the right of me is a nice juicy and totally empty sidewalk, because nobody walks up here, everything is too far apart. So occasionally, when I am really nervous, I have ridden on that empty sidewalk.
