Aligning triple cam not really difficult at all - I do remove it from time to time to clean the dust in front of it and free play is very minimal, which, I suspect, gets adjusted by driving calibrationYes, probably camera alignment is paramount and only those mobile service teams who has these skills can perform this. I once had mobile service switch out my main tripple cam via mobile service as there was lot of dust inside and I told them I'm comfortable to activate AP with so much dust in the main cam.
