On orders from Elon Musk, Tesla employees implemented driving range calculations that fakes a longer range in the beginning of your trip and catches up with reality as you approach your destination.

The effect? When potential buyers take a new Tesla on a short test drive, they only see the inflated range numbers, and are fooled into thinking Tesla's perform better.

Dare I say… it is almost as if Elon Musk is not an honest man.
