While driving approximately 70 mph in the hov lane of the 405 fwy, an error message appeared stating that the car was in "neutral". i tried to shift it into "drive" but it would not respond. since there was no room in the center divider to pull over, i coasted as safely as possible to the right through 5 lanes of traffic and stopped on the right shoulder. i restarted the car and it ran fine after that. there was a message indicating an ev system error and indicated i should immediately take the car to an authorized dealer, which i did. the dealer replaced the motor and the problem has not returned. *tr
