I will use the sidewalk when approaching a busy high speed intersection so I can cross as a pedestrian using the cross walk. These are always larger sidewalks and I slow down a ton so I haven't had any problems and seems like what the bikers do.
Otherwise I am in the bike lane/bike path/gutter/road. For places I go to a lot I've found routes that are mostly along non busy roads where it's more chill. Where I am the rules are just the same as for bikes. I have considered ebikes, since the range on those are comically long.
The change in cell phones is truly unreal.
Just really hope the cell phone software catches up and is less trash as time goes on.
