A few years ago I had the pleasure of taking a Mercedes E430 up to 135 MPH for a stretch. It was smooth as silk, no amazing tunnel-vision or 2001 Space Odyssey visual effects. ;)
I felt like I could ride like that all day. Pretty spooky.
The next time I took it to the shop I jokingly told the mechanic that it had a slight shimmy around 122 MPH. He expressed serious concern and said he’d check it out.
You must have been in open desert. Trees arching over the road cause the visual effect at 120 and above, particularly at night.

My 300E 4matic was always drama free at any speed.
