Not that bad.

TESLA SUBZERO WEATHER PACKAGE + HVAC ENERGY CONSUMPTION
Energy consumption has been broken down by feature. Total energy consumption can be added together based on the number of features that are enabled.
Assuming a consumption of 333Wh/mile, we can compute the approximate range loss at miles per hour (mph) as a result of having these heating features on.
Baseline (vehicle at rest but powered up): 247 Wh = .74 mph
Defroster (rear window & side mirror heaters): 285 Wh = .86 mph
Steering Wheel Heater: 95 Wh = .29 mph
Heated Wipers & Nozzles: 95Wh = .29 mph
1 Seat Heater: 57 Wh = .17 mph
2 Seat Heaters: 133 Wh = .40 mph
3 Seat Heaters: 171 Wh = .51 mph
4 Seat Heaters: 209 Wh = .63 mph
5 Seat Heaters: 247 Wh = .74 mph
HVAC at ‘HI’ or 82F (28C): 6.4 kWh = ~18-20 mph
HVAC at 74F (23C): 342 Wh = 1.03 mph
I need freeper help talking my rich son out of buying a $75,000 tesla this week.
Is there any evidence that values will plummet soon?
Is there any self driving cars that use regular gas, and not electric ?
