I ride my bike 5-6 days a week though town at different points, using a combination of bike lanes and the sidewalk as necessary. Motorist don't bother to check frequently when turning left or right turning off. If you are walking or riding on the sidewalk going down the one way motorist don't bother to look the opposite direction of the one way. Almost every day I stare at someone not even looking at the crosswalk until they acknowledge me or make the turn. 

Sure one or two may be doing whatever they want but most of us like not dying or being severely injured by a vehicle since we are on bike, since you are not running that risk in your vehicle.
