I see it all the time people changing lanes without checking their mirrors. The GirlFriend had a front row seat this day....
Any time I'm in a situation as the black civic was(lane to my left, approaching a big slow vehicle on my right), I would preemptively move left just in case that would happen. Avoids a lot of BS! Comes with the experience.
He had a free lane to the left (albeit closely following a truck [which he could then move back over after passing the big rig to his right]). If paying proper attention, you would have noticed that grey car to the right, and MUST assume that said grey car will maneuver recklessly.
When on bike, I would be hugging that left white line, which would basically allow that car to fully make that same mistake without hitting me.
That second video, the truck should've had a mental image of who was coming up behind him. People are too occupied with other things, or just staring straight ahead.. I am looking in my mirrors and around with my head almost more often than straight ahead! Again, as you saw someone go around that slow, left-lane-hogging Honda Element, you must assume the truck is next to follow. Preemptively move right, like the van did. There's free territory over to your right!
Yes, people are dumb as hell. This is why I want a camera in my car and LLV every day to protect me when someone does **** like this. You must get videos like this often. Be safe!
Damn, I've seen videos like that before.. Bouncing tires are terrifying, there's no assuming anything on those ones!
