Maybe it's just me, but I never look for the driver's eyes. Mostly because half the time they aren't visible because they are looking at their phones, or passengers or off in la la land. I always looked at the wheels/tires. If they are moving, the car is moving. Unless of course the brakes are locked up and they are sliding but that's pretty apparent too
For me, and apparently Romans as well, makes reacting happen a bit faster.
I had an almost devastating event unfold once that had me off my bike and yelling through the other person's window at a red light. My bike is not quiet. By any stretch. I was in my lane, cruising along and some jackwagon was beside me in the other lane and was on his phone texting while driving and decided to change lanes mid text without a look, signal or anything. I ended up veering into the median and back onto the road behind him luckily without laying the bike over or worse.
Yes I lost my cool and called that guy pretty much every expletive in the book, but he knew he messed up. For me I was glad that I have the habit of looking around at other drivers constantly and anticipating what they may do. The fact that I saw him on his phone alerted me that something could happen and just as I slowed down to let the texter move ahead (so I could keep a better eye on them) they decided to merge. Of course there were no cops around (here it's against the law to even hold your phone to your ear. Has to be hands free or it's a ticket) but there never are when stuff like this happens.
Funny thing was as I was getting back on my bike after loosing my cool, I walked past another car and the driver said "You shoulda hit him". I said "nah he got the point" and left it at that.
My point is, being alert and as TX stated "assume the idiots are going to do the wrong thing regardless" has saved my bacon more than once. I just didn't have a helmet cam to capture it all like Romans did.
Oh btw Romans, I ended up watching all of your vids last night after the video linked to in your original post here. Good stuff Brother.
