> It seems like everything about automating a truck would be more expensive (cost of 1 truck = 5-6 cars)

Isn't that a good thing for adoption?

Here in the agricultural industry, self-driving technology can cost tens of thousands of dollars to add it to your equipment. But when a tractors cost hundreds of thousands of dollars, it seems like a drop in the bucket, so the buyers are willing to put down the money. You don't see many tractors around these days without it.

On the other hand, tens of thousands of dollars on a $30,000 car, potentially doubling the purchase price or more, makes for a much more difficult pill to swallow.

Humans aren't exactly well known for their rationality. Even if the technology provides tens of thousands of dollars worth of utility to the car owner as it does to the farmer, many will struggle to accept paying 100% more for the same car plus one more feature. Farmers see it as a 5% increase in price for one more feature, so, hey, why not tack it on?
