i’ve had a vehicle roll down a hill because the parking brake wasn’t sufficient.
so, wheels turned towards curb, parking brakes and tranny in either first or reverse always. it’s muscle memory at the point
i don’t ever remember the lane keeper in the bronco nudging.
it definitely shakes the wheel.
my vw, on the other hand, is much more aggressive.
a family member asked if the vw was self steering.
reminded her to use the blinkers when shifting lanes!
actual winter tires with real winter tire compounds make all the difference on black ice.
most three peak/snow flake tires aren't made with the winter compounds
you're expanding far beyond the OP's original concern.
the vehicles in your example aren't even moving in the same direction and collide in pretty much a worst case scenario.
a head on collision between a F150 and an 2004 chevy cavalier are very different from the PIT maneuver described by the OP.
unlikely to have a rollover in this situation
the faulty assumption here is that the MY21-24 and MT25+ ECU's are programmed the same way.
if the OP can replicate this behavior at will on his '25, pulling the ASS mod should be pretty definite indicator whether it's interacting properly with the newer ECU
without knowing exactly what and how it was installed, that might be a bad assumption.
it still would be my first item on my troubleshooting decision tree
at this point, i'd remove the ASS eliminator and try to replicate your issue.
that ASS eliminator is messing with the inputs to the engine, so best to eliminate it as a cause before you head to the dealer
