But starting the car takes a couple of seconds (engine turn over isn’t instant) so you would then need to double check your mirrors and blind spots anyway. I’ve been driving longer than most people on here have been alive and a lot can happen in 2 seconds at busy parking spaces. And if it’s somewhere quiet, then you don’t really need to watch your camera like a hawk.

My point being, 5 seconds might sound like an eternity on paper but I’d wager it’s not nearly as impactful once you start factoring real world scenarios.

Personally, I never look at my camera. I just listen to the beeps and watch my blind spot. Not because it’s safer not because of any delay in the camera coming on, but simply out of habit. So I’ve never noticed a delay in the camera coming on. Maybe there isn’t even a delay in my particular car — but if there was, I wouldn’t know.
