Press Stop Underway, Automatically Shifts to Park???

I agree. In my 2015 Camry that has manual override for the transmission, it won't let you downshift too much if your speed is too high. It just beeps at you. Once your speed drops sufficiently, it will let you downshift some more. I use it all the time to save the brakes.

EVERYTHING on these modern vehicles is monitored by its internal babysitter!
