It would be useful to be able to give the car a clean while waiting. Maybe a long reach vacuum hose for the inside carpets etc. Good way to kill 35 mins. An over head shower for the exterior? Cloths could be purchased via a vending machine or bring your own. Could be great for Tesla to have the vast majority of their cars looking clean and tidy on the road.
On my Model S, I can set the height to which the back hatch will open. I have it set so that it can open in my garage without hitting the ceiling. It would be nice if the car could use the GPS and only limit the height when I am home. That way it would open all the way when I am not in the garage.
I know you can auto fold mirrors by location. It would be useful to be able to auto fold them from a point A to a point B on narrow streets/lanes that you regularly drive.
Have a notification that lets you know you left your phone on the charger pad when you leave close the door and leave the vehicle. This becomes important when your phone is the key and you depend on it to automatically lock when you leave the vehicle. So many times I have to run back to car to get my phone.
I used to live in Texas and anyone there knows how challenging it can be to keep groceries cool by the time you get home. A refrigerated frunk would solve that issue and be another selling point. It would be great for campers too.
Add a video player in entertainment mode to play personal videos from USB.
Add air-conditioned seats for hot summer days and long journeys
I noticed people have to lower their car's door glass to speak while using drive-through restaurants. If there is a speaker near the side glasses or anywhere near the side glass as per design convenience, it would make the customers more convenient. Since in peak times, there is a long gap between giving an order and getting it.
I can set the trunk hatch to open in my garage and not hit the garage door, but when outside of the garage and in the car and I open from inside the car for my wife or kids to place on item in they always hit their heads on the hatch. I'd like to be able to long press the screen control button to open to full height and not over write the garage height. And then close as normal.
Underground parking places are usually very narrow.
Summon would be very useful, but it doesn't work because of internet loss and lack off precision.
In these cases, Bluetooth connection should be an alternative way off connecting and enable summon.
Its the connection used to unlock and drive the car - it must work to summon your car.
Make some kind of apps store like apple a tesla store where you can buy new games or app approved by tesla
When its a hurricane and deep rain is hustling to clear the water off your windshield, it would be nice to teach the wipers to chill a bit when the vehicle comes to a stop.
