111 mph is ~150fps

It's a freeway. Everyone is going the same direction. Speed differential is what matters, and it was only around 45mph. You drive 45mph past parked cars all the time and don't blink an eye. All it takes is one parked driver to pull out and it's all over for you, apparently.

It is exactly the problem.

You people making shit up is the problem. You're literally sitting there imagining scenarios where you can feel threatened by a man sitting on a 400 - 500 pound machine, who is traveling at 45mph relative to you. You're ignoring the actual situation being discussed and inventing scenarios in your head so that you can feel threatened and express your righteous indignation while clutching your pearls. It's really weird.

So the "victim" you describe, the guy blindly merging without adequately paying attention to their surroundings and causing a crash.

That guy is the problem.

I see this often. Going that much faster means an average car still in the other lane simply will not be in the motorcyclists lane at all before the bike passes. The bike will pass while the car just has its tires on the line. The motorcyclist is looking ahead for vehicles already in the same lane. Higher risk? Obviously. But I'm tired of people acting like they're a victim because a bike blasted by and they think "I could have killed that biker" (or "that biker could have killed themselves on my car") while barely on their second signal flash. They traveled 10 car lengths, you got your tires on the lane, they pass, you complete your lane change, they're now 30 car lengths ahead.

That situation does not crash the bike into the changing car. It either makes the bike swerve out into a median or the bike passes without incident. The actual cause of speeding bike crashes in traffic is weaving when dipshits riders switch lanes and inadvertently box themselves into a dead end.

Want to avoid lane-change crashes of any type? Change lanes smoothly and predictable. Use your signal, take 4 seconds to change on the highway, and do not swerve to grab the faster lane every 15 seconds. Be predictable, go home without a collision report. You don't have to give motorcycles special treatment but collision avoidance works the same.
