Eye contact is not a guarantee. I was recently coming down a hill on my commute home. The car stopped on a side street (he had stop sign) appeared to look right at me. I was certain of eye contact. He proceeded directly into my path. I locked up the rear and dropped the bike (amazingly stayed on my feet) and watched him miss me by a few feet. (I have a bright headlight and was wearing super bright day-glow yellow jacket. It was day time)
