Honest question about Seattle area drivers

I know this is rant-y but I sincerely do not understand how many of the drivers in this area passed the road test portion of their drivers licensure requirements. Are these testers being bribed??

This past week I’ve seen people drive the wrong way in a roundabout, blow their Yield signs, skip their turns at four way Stop signs, come to complete stops on the HIGHWAY, slam on the brakes in the HOV lane (bc apparently you will be shot dead if you are a solo driver), etc.
