&quot;Tech Package with Autopilot&quot; used to be a $4,250 option including a bunch of small features such as LED cornering lights, fog lights, and a rear trunk that opens remotely. I don&#x27;t know whether all those differences were actually just access-controlled in software.<p>For the autopilot features, the difference was only software. Even before the Autopilot option was first available to order in October 2014, cars were being silently shipped with Autopilot-ready hardware for several months. For those cars, it&#x27;s possible to call up Tesla with a credit card and enable the feature over the phone.
