How does a recall work when the feature that's at fault is software and the platform is able to be updated over the air? I can see pushing a feature flag to disable full self-driving until a service pack comes through... or does one need to actually take their car to a Tesla dealer or can you just connect via WiFi (or wired internet?) while the car is parked?
