Anyone experienced a faint burning smell entering the cabin, like that of plastic, when going 100mph or more?
It's not oil, and I don't see anything burned in the engine bay.
Started smelling this when I hit 120mph, slowed down to 95mph, went away, slowly increased speed to 100-105mph, and started smelling this again.
I have a HUD, warning me if I hit 95mph, so keep it at below this speed for now, until I know where the smell comes from...

If you have anything non-OEM, such as an oil catch can with plastic parts, that would be the place to start.
As a test, try turning off the HVAC. It is unlikely but check the blower motor wire harness for evidence of overheating. I only suggest this because a prior vehicle had melted its blower wire harness; but that was due to corrosion.
