Please don't try to shame people into doing things that they don't feel comfortable with,or that are actually dangerous. You don't live here,so you don't know what our traffic conditions are like.
Well said.
On my daily commute I ride the edge of the pavement of an access road in the morning going with traffic, coming back in the evening I ride about a half-mile of sidewalk against the direction of traffic. Pedestrians are few, especially at night, and I give them the right of way.
Another 50 yard section at the very top of a steep hill in the morning I get onto the sidewalk, stop in a driveway to look back, and then cross four lanes of traffic to get to the sidewalk on the other side and ride against traffic on that sidewalk through a busy intersection and then 70 yards across a major highway overpass. After the busy intersection on the other side of the overpass I stay on the sidewalk against traffic a short distance further before turning left into a quieter area and resuming riding on the street again.
Works for me. If I were to stay on pavement I'd have to contend with right-turning traffic at that intersection while laboring uphill, then ride across a busy overpass with narrow lanes, once past the overpass I'd have to get over to a left lane across two lanes of traffic in a busy commercial area.
Coming back on that same stretch I ride the pavement, with a fast downhill roll on the steep hill.
Traffic law enforcement re: bicycles in my area is essentially non-existent, hardly anyone is on a bike. But neither do I ride like an idiot.
