Yeah - no sidewalk hate from me either.
I don't care if pedestrians don't like it (though on the few occasions i ride the side walk i do slow down and remain hyper vigilant).
I am going to travel where it's safest for me. And sometimes it's not on the road/street. Heavy traffic areas on fast-moving roads, boulevards, whatever are not always safe. If i were struck by some 4,000 lb behemoth and the driver was technically wrong i'm still in the hospital and owning a destroyed bicycle.
No thanks. I'll risk hurting some snowflakes feelers 1st.
