It’s probably less than 5 seconds in perceived terms. Eg the car gets power before the engine turns over, and you then need to select reverse after the engine is running. And you’d need to check your blind spots before checking the camera too. So by the time the driver is ready to check the camera, it might feel like a much smaller delay or even no delay at all.

The delay that I notice the most is the time it takes to connect to my phone via Bluetooth (usually so I can play music from it). I’m often already pulling out of my parking space before it connects.

I can change gears in well under a second when moving. My car requires the clutch to be depressed when the car starts, meaning that I can actually ahve the car started in reverse in under a second. Waiting another 4 seconds is crazy.

It could very well begin booting the second the car is unlocked

You’re not going to change gears before turning your engine on though. Which is my point.

And if you’re reversing within 3 seconds of turning your engine on then you’re either driving recklessly or on an open and safe space where you don’t even need your cameras.

To be clear, I’m not suggesting that a 4 second boot time for an embedded device is great. But I do think your claim that waiting 4 seconds “is crazy” is rather hyperbolic.

If I've parked my car, I have to have my foot on the clutch to turn it back on agian. My foot is already on the clutch, and I can very easily (and often do) put my car in gear _immediately_.

Or I've looked in my mirror and put my seatbelt on before I turned the engine on. This is the equivalent of "you're holding it wrong".

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.
