They made it standard after the Star Trek actor died at his house from his Jeep rolling back down and crushing him in his driveway.

@@HealtherSkelter I mean mine still forces the truck into park and flashes the shift knobs lights while reminding me how dumb I am on the dashboard with a message, also flags a warning code in the computer if you do it to often. I see absolutely no reason for a computer controlled fly by wire shift knob to move on its own when all the truck/car needs to do is beep a warning and display a reminder. Then again I often forget about the intelligence level of most drivers these days so whatever I guess.
