VMT is a metric of the total miles travel by vehicles in a defined area over a defined period of time and is often used to estimate the environmental impacts of driving, such as GHG and air pollutant emissions.

Roadster uses about 230Wh/mile at 55mph, we know that Model S 85kWh battery should last 300 miles at 55mph. That gives us 283Wh/mile. Difference is 53Wh. Roadster uses about 330Wh/mile at 75mph, so Model S should use 383Wh/mile at 75mph. 85kWh/383Wh/mile = 222 miles. Estimation, but should not be far from truth.
