The car manufacturer has confirmed that while the default setting requires the service to be manually enabled and lane changes have to be confirmed, it's not set in stone.
In a lengthy blog post, Tesla explained that there will be three additional settings - Enable at the Start of Every Trip, Require Lane Change Confirmation and Lane Change Notification - featured in the Autopilot settings menu.
The post read: "Through the Enable at Start of Every Trip setting, Navigate on Autopilot can be set to automatically turn on each time a driver enters a navigation route.
"Once enabled, anytime a driver is on a highway and uses Autopilot with a location plugged into the navigation bar, the feature will be on by default.
"If a driver selects 'No' to Require Lane Change Confirmation, lane changes will happen automatically, without requiring a driver to confirm them first.
"Drivers can elect to get notified about an upcoming lane change by receiving an audible chime as well as a default visual prompt. Additionally, all cars made after August 2017 will also have the option to have their steering wheel vibrate for the alert as well."
