I lease a Tesla Model S and my app currently advertises all of this for "Full Self-Driving Capability": "Navigate on Autopilot", "Auto Lane Change", "Autopark", "Summon", "Smart Summon", "Traffic light and stop sign Sign Control", "Coming Soon: Autosteer on city streets" for a $15,000 upgrade.
There's a separate $6,000 "Enhanced Autopilot" upgrade option that covers the first five features ("Navigate on Autopilot" ... "Smart Summon").
That's all the detail I get. I presume that at least auto park and summon are unlocked immediately, because those worked on my previous leased Model S without being in a beta. The the first feature "Navigate on Autopilot", which is in both options, sounds like has to be an over-sell. How that doesn't imply autosteering is beyond me.
If not presumably they could argue that they never received what they subscribed to.
