If you want to use the
preheating feature before arriving to a Supercharger, to save time when charging,
this feature is activated only when you choose this Supercharger as a final destination.
If you use the trip navigation, and a Supercharger is included in the generated itinerary list,
the preheating will not be activated.
I don't know exactly how long time in advance the preheating occurs, but in general I change my navigation
from full trip to Supercharger destination about 30 minutes or 30 miles in advance.
I spent a lot of time using ABRP in advance to optimize my trip itinerary but during the trip I mostly rely on the Tesla navigation,
because
the Tesla energy consumption is very great a determining when you should stop at a Supercharger. As you mentioned,
there are so many parameters, such as weather temperature and wind direction, elevation, traffic,
but mostly speed, affecting the consumption.
I area with low density of Superchargers, don't skip any of them, because you never know what could happen, such as an accident
keeping you stranded or forcing you to make a log detour. In this type of locations, I always charge like to 80% and never go below 25%.
In some areas the speed limit is 80 miles/h, so this means that every one drives like 85 miles/h and above... affecting strongly the consumption.
I would recommend
looking at the location of any Superchargers on your itinerary, even those that you don't plan to stop by.
Using
Tesla.com/Findus right on the link "Driving Direction" on any Supercharger. This will open a Google map.
I like to analyze by myself how to access and exit from a Supercharger using "Google Direction".
The Tesla Navigation often makes you doing some complicated detours. This might not the case in rural areas,
but this quite common in urban areas. (For example, when exiting a Superchager, the navigation, if you are going East,
will only looks toward the East, while there might be an exit on the West just one block away.)
Make a list in advance of the 250 kWh Superchargers, as the Tesla navigation doesn’t try to use those as a priority.
Look at the amenities when selecting a Superchager, and check the opening and closing time. This is important
especially if you need to find a restroom. In general I choose to stay close to Supermarkets as thoses are often
open for extra hours.
I know, you save time by charging often and not above 60%, however if you have passengers, they would often like
to spend extra time shopping or eating. In this case, this will be the occasion to get a full charge, this will often occur in fact.
If you have FSD, I found the automatic lane change very practical and relaxing, especially after passing a big truck
when you try to go back to the right lane, as the rear visibility is not that great. But I prefer to control myself this feature
using the turn signal, and I don't like to have FSD trying to constantly changing lane to stay at the setting speed.
