I ride up and down Benson daily, and every day this happens at almost every cross road when I am west bound( against flow of traffic, sidewalks are bi directional) Drivers roll forward or turn right with heads turned to left. I shout or whistle until I have eye contact, the majority realize they were not looking for anyone on sidewalk or are in the crosswalk when crosswalk user has right of way. If no eye contact or tinted windows I stop whether I have right of way or not. This guy was upset because every single day someone who does not obey the LAW and look both ways tries to kill him, the frustration is real. Do you know what it is like to have people try to kill you through ignorance every day?
 I used to do this same stupid thing as a driver. Ride a bike and you will never see driving or city planning in the same way. the bright point of your story is you will always look now...
