If you do that, you’ll also get a handle on what ‘self-driving’ abilities your car has. This gets complicated, because the Autopilot system (which includes lane-keeping assistance and adaptive cruise control) has changed definition and names down the years and didn’t always come as standard.
You may also see Full Self-Driving Capability, which allows the Model S to park itself, change lanes on the motorway and even be controlled at very low speeds from a smartphone. Plus, it enables the car to recognise stop signs and traffic lights and come to a standstill. It will also be able to use Autopilot to navigate around cities – once the tech and law allow.
You need Autopilot 2.0 to support Full Self-Driving Capability, so a car built from late 2016 onwards. And even if the Model S you fancy doesn’t have this tech, you can add it over the air for a fee.
