https://en.m.wikipedia.org/wiki/Sweetening_(show_business) gives a quick rundown.
In television, sweetening refers to the use of a laugh track in addition to a live studio audience. The laugh track is used to “enhance” the laughter for television audiences, sometimes in cases where a joke or scene intended to be funny does not draw the expected response, and sometimes to avoid awkward sound edits when a scene is shortened or more than one take is used in editing.
To be fair, Tesla autopilot does a decent job killing people in civilian applications so this feels like a natural move.
