Twice recently while driving on highway at night, the car computer started failing. lights went out, turn signals didn't work, eventually the whole screen and dashboard that let you drive turned blank. i had to find a way to quickly pull to the side of the road and reset the car by pressing and holding the two buttons on steering wheel. this is a very unsafe condition.
Backup lights are inadequately bright at night, in dark situations allowing no ability to make out ground features when backing up. tesla has updated firmware and replaced camera with no improvement. safety defect of being unable to see behind car when backing up at night not fixed, seems to be a design problem with the car.
