> But riding on the sidewalk really does mean that the burden of taking care of pedestrians is all on me.

The thing is, I have more trust in my ability to watch out for pedestrians than I trust drivers to watch out for me.

Fun fact: After I started wearing a reflecting vest when riding my bike, I think drivers have treated me much more considerately. Maybe they are not so bad after all and just did not see me as easily before.

I disagree. If you were biking around staring at your phone and weaving into oncoming traffic, is that someone else's fault?

Being in a public space necessarily means exercising a degree of care and consideration for other people. From everyone.

No, because the law states that a bike on the road with cars is equal to other vehicles and has no higher priority in regards to right of way.

In contrast, a biker on a sidewalk is not considered equal to a pedestrian. In fact, it is illegal in most cases, but probably not illegal or dangerous enough to warrant strict enforcement.

I consider pedestrians to have just the responsibility of paying attention to their surroundings to not inconvenience other pedestrians, not bikes or scooters.

In Washington State this depends heavily on municipality and you need to know exactly which cities you're riding through. State law only says that you have the same duties and rights as a driver when on the road, and that you have the same duties and rights as a pedestrian when on the sidewalk. When I rode to work I checked all three of the cities I rode though and they all allowed bicycles on sidewalks.

I generally choose whew to ride based on the density of traffic. If nobody is on the sidewalk and the sidewalk is in good condition I'll ride on the sidewalk.

I feel like this is the key distinction. I strongly prefer riding on roads, even when other people think it looks unsafe, for the simple reason that people on the road (generally) follow rules. You can, within reason, tell well in advance what someone is about to do.

I feel much safer in an environment where there are clear rules of engagement that are, by and large, respected.

(Anecdote: my most recent crash was with a scooter, the rider of which was very inexperienced in traffic and reacted to a tight spot by doing exactly the opposite of what they teach you in driver's ed. Feel free to guess whether this was on the road or on a bike path...)

Where I'm riding it is completely legal to bike on the sidewalk, so it's not something that should be unexpected.

> I consider pedestrians to have just the responsibility of paying attention to their surroundings

This is what I'm talking about. Many people cannot even be bothered to do that. If you aren't going to take an interest in your own safety, why should anyone else? The sidewalk is not the place to zone out and lose yourself in your Twitter feed.

I'm not sure where that commenter is posting from, but isn't cycling on the sidewalk _illegal_ in most places (except in sidewalk-inset bike lanes)? It's quite reasonable to walk on a sidewalk without expecting bikes to hit you; they shouldn't be there in the first place.
