Tesla Touchscreen Redesign for Fewer Eyes-Off-Road Glances, With No Feature Lost

You are a product manager at Tesla. In Tesla's vehicles, most driver-facing controls run through a large central touchscreen rather than physical buttons. How would you improve the in-car interface so that it pulls the driver's attention from the road less, while every function it offers today stays available? ```hint Inventory the in-motion tasks Before sketching screens, list what drivers actually do on the interface while the car is moving, and sort those tasks by how often they happen and how urgent they are. A control used on every trip calls for a different fix than a setting changed once a month. ``` ### Clarifying Questions - Does "without limiting functionality" allow moving a feature to another input (voice, a steering-wheel control, the phone app) or to use only while parked, as long as it stays available? - Is the scope software delivered over the air to cars already on the road, or can I also propose hardware changes for future models? - Should I focus on manual driving, or also on moments when driver-assistance features are engaged? ### What a Strong Answer Covers - A measurable definition of distraction (glance length, total eyes-off-road time, steps per task) and a clear reading of the functionality constraint - An inventory of in-motion tasks grouped by frequency and urgency, with the pain points that cause long glances - Solutions matched to task types (fixed layouts, wheel or physical controls, voice, automation, passenger and parked access), prioritized by impact and delivery cost - A validation plan and metrics showing distraction fell while every feature stayed usable - Trade-offs and risks: muscle memory broken by software updates, automation errors, hardware cost and regulation ### Follow-up Questions - Which single task would you fix first, and how would you prove the fix shortened glances at the screen? - Some safety-rating programs now favor physical controls for core functions. How would you respond if that conflicted with Tesla's minimal cabin design? - A driver complains that a feature now works only when parked. How do you decide whether that counts as limiting functionality?
