This clip is listed as 'Let's Go' from the Cars song, and its appeal comes from that simple, instantly recognisable call to action rather than any complex lyric or melody. Short vocal hooks like this travel well on soundboards because they are easy to recognise, quick to reuse and clear even on a phone speaker. Once creators started using it as a launch cue for driving, racing and travel edits, it became a handy shorthand for getting started. Its brevity keeps it useful, since it can open a video without taking over the scene that follows.
