Re: Teleporting trucks
Sorry but "partially concealed driveways" just means that the visibility is too low for the road speed.
A sudden rockfall, a bridge collapsing in front of you M20 style, or a 400kg hay bale bursting through a fence because some idiots wondered if it would roll down the hill, yes that's an unavoidable problem, for human and robot alike, although the latter will always be able to react quicker.
Driveways, however, are not camouflaged. Even if the rare corner is completely blind, there is a speed at which it can be negotiated with near-zero lethality. Remember, metal is only metal --- driving into the back, side or even front of the truck that has mysteriously teleported into your field of view at 20mph is probably not going to kill anyone. In fact about most pedestrians could survive a hit at this speed.
