 becoming almost standard for every new vehicle with cameras and so helpful when navigating in tight spaces : 360 degree surround-view as a virtually assembled picture of all cameras. 

Please add a max speed function in addition to cruise control.

This makes driving in cities much more comfortable. With a Tesla you’re quite easy over speed limits...

It would be really nice to have native apps for playing music from Apple Music, Spotify, Google, Amazon, etc. Slacker really isn't the best

Please add normal Cruise Control without Traffic Awareness. Preferably with steering wheel button support. Set, Cancel, Restore. Using the buttons is less effort than using the stalk.

Activating and using the Wipers requires too many touches and is a distraction to driving requiring the driver's eyes to be on the touch screen instead of the road ahead.

I can't tell you how many times my wife has gotten in the car after my kids have adjusted the passenger seat and she has to fix the seat back to how she likes it. Another profile button for passengers to save settings would be great.

You know how Google maps shows you alternate routes in gray with +/- time differential in typical app-view on your phone? I would love to see that in our nav view!

For those of us where bike lane splitting is legal, allow to set the AP to hug closer to left or right of the lane to make a larger clearing. This could be only for slow speeds in traffic. 

I have my first trip meter (Trip A) changed to Lifetime so that I can keep track of my usage over time. But I worry that I or someone else might accidentally reset that trip meter.

In the Model 3, you can currently set a START TIME for charging. It would be nice to be able to add a STOP TIME as well, to prevent your car from charging when electricity rates may be higher. Also build this charge scheduling feature into the app.

More details:

When letting off the accelerator quickly flash the brake lights to warn a driver following closely that you are slowing down. 

Display a braking indication on the touch screen when the rear braking light is on or off.

I know that transparent solar panels are in development. Putting some of them into the big glass roof would have three big benefits.

How about using the wheel button to scroll through manual wiper settings? This way a driver can keep his eyes on the road. Automatic wiping kicks in too late, and I find myself fiddling with the screen on moments where I want to keep my eyes on the road (heavy instant rain).

The location based mirror folding preference seems to fold the mirrors as soon as you arrive at a location even while you're still reversing into the parking spot and still need to use them. Do not autofold mirrors until the vehicle has been put into park for at least 3-5 seconds.

The preconditioning feature should be extended to non-Tesla CCS fast charging. A button to start battery preconditioning manually should be included. The user can activate precondtioning when approaching a non-Tesla CCS charger.

Tesla needs to implement a feature that dynamically allows the setting of a temporary speed limit. A feature often found on European, but sadly almost never found on American cars.

As per the description of Volvo:

When charging at a destination charger (such as a hotel) it would be ideal if there was an option for the charge port to automatically unlock once the vehicles reaches its target state of charge (SOC).  This would allow others to use the charging cable without requiring the vehicle owner to (remo

Scenario:

Me and wife get into car. Both phones were set up previously for media/calls. Only one phone get's connected for media and calls. Let's say it was mine. Both phones are in phone holder and closed. Wife receives a call.

Problem:

Ever got annoyed by the bright blue-white light coming from the center display?

When driving in Autopilot, and the speed limit drops, it doesn't slow down until the car has passed the speed limit sign, and when it does, it does so abruptly.

offer a 15’ extension cable to allow nose in SuperCharging.  When towing it can be a real pain to unhook a trailer so you can back in to charge.  Double the pain as one’s range is effectively cut in half when towing.

It's weird that to turn off your headlights (say, at a storefront or a security booth), you can't just tap the headlight icon instead of navigating to a menu entry.

Currently I have to manually fold the mirrors every time I enter and exit the garage due to a tight fit. I wish it would auto fold when arriving and auto open the mirrors when leaving(Door closing). 

On many Public 3rd Party Chargers it would be more convenient to have an additional charge port on the Co-Driver side of the car.
Especially 
 

Add a 2nd charge port on the other side!
