While technically true that extra sensors contribute noise, surely with the proper programming they should be helpful. You just need to weight the information from you extra sensors appropriately based on your confidence the signal is accurate.

For example, if your lidar sensor is 99.999% percent sure there is an obstacle in front of you, surely it's helpful to take that information into account, even if it is a tiny bit uncertain/noisy.
