Regrettably, this is not an uncommon sight in our area, whether on a pedal bike, e-bike, or motorized bicycle. Drivers at intersections have been conditioned by years of experience to focus on areas where they expect conflicting traffic to appear, and not spend time looking in directions where they don't expect such traffic to appear (such as at high speed from a sidewalk in the opposite direction of traffic). When these riders crash at intersections, driveways, or other locations, the number of reported bicyclist crashes then is publicized as showing the metro area is "dangerous for bicycling". In some cities, wrong-way sidewalk riding is legally ambiguous or expressly permitted. And many police agencies don't see traffic enforcement of any bicycle laws as a priority, especially where organized groups of motorized bicycle users have complained to elected officials.
