ah yes because the method of shopping with a basket and things being underneath other things is just completely not a thing that'll happen, and the shitty implementation would always have perfect visibility on every single item and line of movement. no camera obstructions could ever happen, no light problems could ever come to the fore! perfect visual analysis! just like how we already have self-driving cars purely on optical sensors!

(your comment is bullshit, go learn some shit)
