Lights?
- YZF 4y agoA car typically doesn't have lights shining in all directions. My Tesla doesn't at an rate. At night, backing into my driveway, I can barely see anything on the back-up camera unless the brake lights come on. If it's raining heavily it's much worse. But the ultrasonic sensors are really good at detecting obstacles pretty much all around.
- throwaway09223 4y agoReverse lights are literally mandated by law. Your Tesla has them, and if they're not bright enough that's a fairly cheap and easy problem to fix relative to the alternatives. Ultrasonics struggle in the rain, btw.
- YZF 4y agoThe sensors also detect obstacles on the side of the car where there's no lighting. Every problem has some sort of solution, but removing the ultrasonic sensors on the Tesla is going to result in poorer obstacle detection performance. Sure, if they add 360 lighting and more cameras they can make up for that. EDIT: Also I'm not quite positive why the image is so dark when I reverse at night. But it still is. The slope and surface of the driveway might have something to do with that... Still I wouldn't trust that camera. The ultrasonic sensors otoh seem to do a pretty good job. That's just my experience. EDIT2: I love the Tesla btw. The ultrasonic sensors seem to work pretty reliably, they're pretty much their own system, the argument about complexity doesn't really seem to hold water and on the face of it the cameras won't easily replace them...
- cbsmith 4y agoInteresting. I find the rear camera in my Tesla is outright amazing in the dark. I can see objects so much more clearly with it than with the rear view mirror. It feels like I'm cheating... almost driving in the day.
- somat 4y agoJust curious, do teslas have a reverse light?
- kwhitefoot 4y agoYes. Only one on my 2015 Model S 70D. Not sure how many on other Teslas.
- Eric_WVGG 4y agoI just assumed they used something similar to iPhone FaceID and Xbox Kinect dot emitters. https://www.theverge.com/circuitbreaker/2017/9/17/16315510/iphone-x-notch-kinect-apple-primesense-microsoft https://www.theverge.com/circuitbreaker/2017/9/17/16315510/i...
