I was just at the Menlo Park dealership and they had 4 S' there. Including beta 49, I spent A LOT of time with it. The car is really incredible, but it led me to ask the question, what is still unknown about the car? I figured we can make a list and cross things off when they are figured out! Unknowns: 3G/4G connectivity: LTE? Carrier? Cost per month? Will their be hotspot functionality? It has a SIM, meaning most likely ATT or Tmobile Convenience lighting: Where is it? When does it turn on? Music control: Can you edit and add to your music library over wifi? What form of iPod/iPhone/MP3 player functionality will it have? Smartphone app: What will you be able to do? Map? Pre-condition? Cost? Live later this summer? Panoramic roof shade: What will it look like? What will it be made out of? Supercharger network: Cost? Locations? One hour charge for 85 ? Homelink: Where is it located? How many buttons? Wiper blades: Will there be a off function? Electrocromatic mirrors: Is the rear view mirror electrocromatic? Is that a standard feature? Keyless entry: Will it be available at launch? Speakers: How bad do the standard speakers sound? "Textile" seats: What will they be like? How adjustable? Badging: How will it be badged? P85? R60? Bluetooth: How will the phone contacts work? A2DP? Center console accessory: Availability? Cost? "Called the opportunity console" Prototypes available to see at the launch event. Service: How much will it cost? What will be covered? Battery degradation covered? Charging locations finder: Can you use the touchscreen to find a charging station- YES? Are they in use or not? Battery swapping: Can you rent a 85 kWh pack for a road trip? And the real big questions: What will the differences between signatures and regular production be? Headliner difference? Seat difference? Actual Performance: What will the ACTUAL numbers be? 0-60? Slalom? Skidpad? RANGE? Things I learned today: The screen and newest software is really, really, REALLY zippy. It was amazing how fast and responsive it was. Air suspension is really cool, noticeable and could actually be useful. The keyfob is awesome, and beautiful. The screen directly in front of the driver has three zones, the speedo and two zones on either side. Those zones are adjustable using the two scroll wheels on the steering wheel. The left scroll wheel controls volume and on/off. Or, you can map it onto the other side. The options were: Phone, Stats, Music, Nav, and a few others. Visibility isn't great on the car. The sun shades are also super small. I CAN'T WAIT! What else do we still need to find out?
