2021 Subaru Crosstrek forward collision avoidance problems

While driving on the highway in the slow lane (furthest to the right), traveling at approximately 50 mph, I came to be behind a tractor trailer. Before I had a chance to pass the tractor trailer, it switched lanes abruptly. My vision past/beyond (in front of) the tractor trailer was heavily obstructed by the massive vehicle itself, so I could not see that in front of the 18-wheeler there was a mid-size sedan traveling at approximately 5-10 mph in the same active highway lane I was in.

My vehicle is equipped with eyesight, which is a subaru technology that includes adaptive cruise control, forward collison warning/breaking, lane departure warning, rear automatic braking, etc. Subaru claims that windshield replacements must use subaru glass due the optical clarity of the windshield and that the eyesight system must be recalibrated. This is a $1339 cost (via safelight) to replace the windsheild. I have 8400 miles on my vehicle, and I am getting ready to have the second windshield put on the car.
