When going on a road trip Tesla calculates the time based on the route you put into navigation.

Obviously it will give a different estimate than stop and go traffic and starting the vehicle without pre-conditioning the battery.

Tesla does a great job with their scheduling functionality that lets you pre-condition battery before you leave and even when you near a supercharger to maximize charging efficiency of the battery.

That makes sense. But if Tesla is going to do that, surely their less informed estimation shouldn't be so naive and use historic data. Why would Tesla guess I'm in stop and go traffic when it knows I spend 80% of my time on a highway. Shouldn't it aim for either the most accurate or most conservative naive number?

As the article points out, it also switches to a significantly more accurate estimation once the battery is half discharged.
