The key card is cool. Tap it to the driver's side B pillar and the car unlocks. Or use the phone app to lock/unlock, set environmental controls (keep the car cool or warm while you are away from it). The card is useful for valet situations and there is a dock for the key in those situations.
Two scroll wheels on the steering wheel whose functions change based on what is selected on the UI. Could take some getting used to, but very minimalist.
