When I order SR+, I was thinking 240 mi, plenty of mileage, I would never drive 240mi a day, and I won't be driving the EV on a road trip, so it should be plenty. What I didn't do the math is keeping the battery within 10-90% meaning my range has drop down to 190 miles. This 190miles also do not mean I can drive for a distance of 190mile. Over the past week, I have experience outside temperature of 40 to 70 degree. Reading the TeslaFi data, at 40 degree (driving mostly at 70mi/h), the car's efficiency can be down to 75%. (short distance efficiency can be as bad as 45% because the battery is cold) I don't know what would happen at below zero. Driving above 80mi/h also hurt efficiency a lot. With 75% efficiency, you will be dealing with 190mi *.75 = 142mile. So my 240mi SR+ is practically only have 142 mil during spring time. I know it will be better in the summer but I can't imagine what happen during winter. After a week of driving, I regret not getting the LR or AWD.
