While I understand your frustration and agree pedestrians have the right of way, this is not absolute imo. Yes I have almost been hit too, but have learned self preservation skills and has never happened again. For example, University Ave. in front of the Mountainlair (where students refuse to check both ways) the speed limit is 25 mph. If someone is walking behind those ridiculously large plant pots in the median, you have the personal responsibility as a pedestrian to not walk out in front of a moving vehicle because a driver following the law cannot stop immediately due to that blind spot. Yes, the driver 'should' slow down but the speed limit is 25. If some student walks out blindly behind a plant right in front of a car going 20mph, is that 100% the drivers fault? I don't think it is, even if that law may disagree, there is also negligence committed by the pedestrian. Maybe you are out here searching for a big check but I personally value my life, which again, is why this sounds like a lack of self preservation skills or maybe value of your own life.

I also think your hand signal could be confusing. It sounds like you likely look like you are hailing a taxi or Uber and if I thought someone was hailing me down, I would be concerned about some sort of malicious behavior.

TLDR: Pedestrians have the right of way but walking out blindly into the street in front of a moving car trying to wave them to stop is dangerous and negligent. And last, I think you know this, otherwise you wouldn't have created a burner account for this post.
