Getting an underbody car wash after a salt coated winter doesn’t help a car? Idk all the gunk in any moving component being washed away seems like it would improve drivability in terms of less friction. But a software update making the car with static suspension ride softer and crash over bumps less seems like v11 hypnosis.This is like people commenting how their ICE car runs better after getting a car wash and clean interior detailed. People swear by it too especially after a salt coated winter.
V11 may have some tweaks in how the motors are controlled but I haven't heard anything definitive on it yet.
