I agree with
@borski that CR purchases the cars they review.
And there would have been no way for Lucid to check a car out before turning it over to CR. As near as I can gather from this forum, pretty much every Gravity has this problem at one time or another, and it occurs randomly and intermittently. So a car may start up fine five times and then on the sixth leave you looking at one, or two, or all black screens.
We had this regularly with our first Gravity. When our second Gravity arrived three months later, the problem seldom presented, so I thought it had been mostly resolved. Then suddenly, on a day I was racing between appointments, the new one shut down completely the instant I pressed the brake pedal, even though everything has powered up properly when I first got in the car. Everything went dead (even the windows and the door latches), just as it did in the CR video.
