These are just general pointers that throughout my ownership wound enhance the overall Tesla Experience:
Tesla needs to assign personal customer service reps. It would be easy for Tesla to assign them like the insurance company's do with a picture of the person, their email, and contact on this website when requesting service or support. Make their information easily available on the phone app as well.
Superchargers need to show inbound traffic and estimated wait time for your arrival and/or stall load on arrival. They also need to have a better reporting system on their phone app that allows users to take pictures of Cars that sit unplugged and are tieing up stalls. I've seen it several times now a car parked and not plugged in at a busy supercharger. Superchargers are getting busier and this information would be very beneficial. It should also show you peak times and estimated load based on your time of arrival using historical data. Maybe even appointments that can be set. Just an idea.
Phone app needs to have tesla trip planner built in that either can be used off user set mileage on car or current car mileage based off battery charge. Getting in the car or getting on a web browser to plan a trip with perfect 310 mile range is old. It needs to do a good job of showing what is around instead of having to look at google maps or search for it.
Tesla needs to have an inclement weather range adjustment that is for the user. Similar to range mode, this mode shows the user how much energy they may potentially save while on a road trip by turning off heat/ac or driving slower.
Tesla needs a "hints" mode sort of like iphone that guides the user during their first week or first experience with the car that is able to be turned on or off. (i.e. WiFi will allow your car to download updates and receive updates quicker than normal LTE).
Tesla needs a lower powered version of Heat that only uses a maximum of maybe 1kw. I wish they could turn the A/C into a heat pump to alleviate with range loss and increase efficiency in winter months.
Any additional please chime in.
