I was driving home in my model x on lawrence expressway (8-lane expressway) in santa clara, ca and stopped at the red light. when the light turned green, i pushed on the gas and noticed that the car did not move and put itself into park. i could not put the car into gear. the main screen flashed several warnings that included: park assist unavailable automatic emergency braking disabled. car needs service traction control disabled. stability control disabled. i put on the blinkers, called tesla roadside and they asked that i restart the vehicle by holding the 2 control buttons on the steering wheel, however by doing so, would stop the blinkers from blinking. i felt that would've been unsafe because i was in lane 2 heading southbound on an 8-lane expressway, and cars were coming from behind me pretty fast. roadside asked that i call 911, which i did, and they then sent a tow truck to get me out of my situation. video of what happened located here https://youtu.be/9i9sghtmd7c
