Speedometer is reading incorrectly, does not match gps reported speed or the play place officers speed when he clocked me going 13 miles an hour over the speed my adaptive cruise was set at. cruise control was set at 76 miles an hour and my phone was not on the gas, the gps on my map application showed i was going 87 miles an hour and that is the speed the police officer noted as well.
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.
Recently i rented a ford expedition. much of the driving was in an around the mountains surrounding yellowstone national park. while i found the vehicle easy to drive there is one glaring safety issue concerning the ability to downshift. one must take their eyes off the road to locate the + or - buttons on the center console to change gears. these buttons should be located on the steering wheel. not on the center console.
