Tesla is about to release software letting cars drive from highway on-ramp to exit, changing lanes and overtaking other cars.

'About to release' is read as a release to customers within roughly the following four months, so by 31 Dec 2018. True: by then Tesla shipped software to customer cars, including as a beta and including driver-supervised use, that drives from a highway on-ramp to the exit, follows interchanges and makes lane changes to overtake slower cars (for example Navigate on Autopilot). Mostly true: it shipped in that window but with a minor limit, such as needing the driver to confirm lane changes. Mostly false: it shipped only after 31 Dec 2018, or only part of the capability (for example lane changes but not on-ramp-to-exit routing) shipped in the window. False: no such software reached customers by then, as shown by release notes or dated reports placing the release later or recording it as cancelled.

Set before the research began.

4. E4 Tesla starts releasing Navigate on Autopilot feature with disappointing caveat, update with UI changes Electrek · 24 October 2018

   “But it is still in beta, and unlike the first version that was released in Tesla’s Early Access Program, the feature doesn’t initiate the lane changes.”

Independent reports from October 2018 say Tesla was rolling out Navigate on Autopilot and that the update was live. The feature guides a car from a highway on-ramp to the off-ramp, handles interchanges and makes lane changes under driver supervision (E1, E2). At release, though, lane changes were suggestions that the driver had to confirm by tapping the turn signal, and the feature was labelled beta (E3, E4). The criteria name this exact limit as an example of mostly true.
