I find the ultrasonic sensors presently in the Tesla 2022 Model Y with visualization and number of inches distance are exceedingly helpful for me in manual parking in tight spaces, parking garages and the like, all situations where autopark does not come close to even recognizing a spot at the moment.
Tesla has quite poor visibility to the rear and front bumpers from my driver's actual view, rear view mirror is virtually useless.
It is not providing a 360 degree camera view visualization and in other vehicles I've driven that do have 360 camera view, that is not as useful to me in manual parking as front and rear ultrasonic sensors at the bumpers which are the outermost perimeter of the vehicle.
Thus, for me, the loss of ultrasonic sensors would be dreadful!
In addition, in metro areas where I drive there a great many concrete road construction barriers for miles at a time! FSD beta drives quite well between them, often only a few inches away: I find the ultrasonic sensors in FSD beta give me a comforting reassurance that the car is not steering too close to a concrete barrier.
If Tesla engineers are reading this, please take a trip out of Texas and California where parking spaces are wide, and park manually sometime in Boston, Paris, New York, London, Shanghai, Seoul!! You will find the precision of the ultrasonic sensors and visualization map objectively are essential in not hitting commercial parking garage walls and columns, or in parallel street parking other cars.
