Car Slowed Down On Its Own problems of the 2018 Ford Expedition

Electronic dial shifter will automatically switch from drive to park if the vehicle start stop button is depressed when the car is running. The parking brake also automatically switches on at the same time. Consider what would happen if a 2018 Ford Expedition is traveling on a freeway in traffic and the start stop button were accidentally depressed. The car would shift into park, the parking brake would engage and the driver would decelerate rapidly from 65 mph to a stop with no notice, likely being rear ended by traffic ie; a semi truck at highway speed. The electronic shifter should stay in the selected gear when the start stop button is depressed as a convention shifter would, electric or mechanical. I determined this after going to a car wash, putting the car in neutral then depressing the stop button to save fuel. The carimmediately shifted from neutral to park and engaged the parking brake. I tested the drive, start button off, immediately switches to park on a flat street at zero speed. I realized as an engineer that if this happened at speed a fatal accident could occur. Ford can remove this risk with a software update to the electronic shifting, leaving the car in the selected gear if the start stop button is depressed.
