you did not what?!That's true, at least not without additional equipment. Don't believe I've ever seen a 'front camera obscured' message. However this is also true of every other kind of sensor though, they're all blocked by something otherwise they wouldn't be any use as a sensor. Lidar uses light, just light you can't see with your eyes, so a Lidar emitter would have the same weakness. It is true that the rear camera on the Y seems quite prone to picking up dirt.
- drive any country road at night - "left pillar/righ pillar camera blocked or has poor visibility" - EVERY TIME.
- drive during winter for an hour and then try to park using rear view camera - good luck with that
- drive during heavy rain/snow - "Speed reduced due to poor visibility" on AP, although I have no problem to see.
- Front camera blocked due to poor visibility when sun is shining
