Earlier quoted context omitted.
Then, the delivery trucks shouldn't be parking there. Clear a spot and turn it into commercial parking only, i say. They're doing this right now on Polk street and it's so much safer for bicyclists on the portions that have this now.
A short detour on a sidewalk or grass/dirt shoulder doesn't seem that dangerous to me. Does it happen much that there's no room on the right and the cyclist has to go around the left of the truck?
1. There's no quick conversion in the middle of the street. It's a curb, which would require hopping, which is nearly impossible for an ebike and a dangerously unstable maneuver anyway.
2. There are cars blocking visibility with the sidewalk. If you hop onto it, you might strike a pedestrian you didn't see. Perhaps a short one, such as a child, who are unpredictable anyway.
3. Going to the right of the truck is a great way to get doored in the 0" of clearance between the truck and other parked cars. If it's the truck, enjoy your guaranteed head injury from the truck door 3 feet off the ground.
4. Biking on the sidewalk is illegal in many cities. So is parking in the bike lane, for that matter. Expecting one party to break the law because of a failure to enforce a separate law is unreasonable.
