In reality, we have Tesla vehicles that sold with other sensors that are now disabled, and those cars are now better to drive with automation enabled than with the extraneous sensors, even simple cruise control is better and phantom braking is actually decreased vs spurious radar returns that existed previously, due to the limitations of low resolution radar. Auto high beams is now better at not blinding oncoming drivers with bright headlights, etc. - issues that happened all the time when other sensors were used previously.
