Mostly Harmless
Agree. a semi truck FSD will require a significantly different training dataset than passenger vehicles. Tesla won't be able to start gathering a lot of this useful data until the semi fleet gets quite a bit larger.
At least that user group does rack up the daily miles more quickly than passenger cars do.
Still, it might take a while for the corner cases, like backing the trailer, accounting for a variety of trailer wheelbases for turning at intersections, navigating a truck stop parking lot, weigh stations, truck specific signage (routes, lane exclusions), etc.
The Jake brake on a Tesla should be very quiet, so those signs can be ignored.
