Your Driving Style and Environment
https://www.tesla.com/support/range
Your driving behaviors and environment play a big role in achievable range. Frequent stop-and-go driving, inclement weather and uphill driving put a natural strain on the battery. To maximize range, it’s important to watch your driving speed and keep regenerative braking in its ‘Standard’ setting, if selectable regenerative braking is equipped on your vehicle.
As you drive, be mindful of common reasons your range may decrease more rapidly:
High driving speeds
Stop-and-go driving
Short trips
Uphill driving
Inclement weather such as rain, snow and headwinds
Do not excessive hot & cold weather shorten battery to miles range?
