Today I noticed my Model S is using 1Mbps of upload bandwidth, interfering with other services. I currently do not have QoS running, although plan to implement that in the long term. I went into the car's privacy settings and turned off the permission to send video and road segment information. I then rebooted. It is still consuming high upload bandwidth. There should be a setting for how fast it can upload stuff, so it can play fair with other devices in the home.
