This is the car I have. (not this exact one)
People always ask me if it's electric. It's not. I paid around $17,500 for it.
The electric equivalent was around $35,000. I get almost 40 MPG with mine.
Do you know how many gas tanks I can buy for the extra $17,500?
I'm sure that a truck like this:Would never pay for itself in terms of fuel mileage. The only way this type of truck would ever work, is if government just flat out subsidizes the cost, just like they do with renewable energy.

Walmart, of all people, has come up with some Streamlined Semi Trucks that seem to have it down pat. It can still haul a normal boxy trailer and it is still stream lined.
It takes some minimal knowledge of physics to understand that a streamlined design allows for inferior consumation of fuel. I don't see many of them living in trailers as the most educated people on the planet.
For the non-trailer living people, those special designs cost more, and they don't see the long term saving as much as they see the "in the moment" expenditure.
It all comes down to lack of smarts.
There are actually quite a few duel saving innovations for tractor-trailers. There are fairings below and above the tractor, wheel caps, gal seals behind the tractor, air skirts below the trailer, some have "trailer tails", there are even GPS connected transmissions which optimize fuel efficiency for upcoming terrain.

There are air deflectors, air Dana, and other devices currently in use on semi tractors.
I have fairings on my tractor for the front of the trailer to divert air flow and some of the trailers have fairings under it too, the tractors are mostly automatic with shift points for optimum fuel efficiency and do get around 8 miles to a gallon of diesel, there isn’t much else they can do but considering how much freight they move for that much per gallon it’s not too bad
Most things people bye comes on a pallet which is square so streamlining trucks would mean less product the truck would carry. It would cause the drive to make more than on trip to the same place or have more than one trucker going to the same place to get tge amount if product that one truck can get to a place now.
Long haul trucks actually are very aerodynamic for what they are, and it is extensively researched for any improvements. Even a 5% reduction in fuel costs is huge for a trucking outfit
If all the "environmentalists" who drive hundreds of miles to protest at this place or that, were to stay home and NOT use their cars, we'd save a lot, too.
I am so glad when I see your questions you come up with some of the coolest stuff
the prices are not too different when considering gas and i would think that for a truck that big the design hasn't been changed for a reason for a long time
I I think you guys have had cheap fuel for along time, it’s not economically feasible anymore, so those prices look similar to ours. The trucks cool too.
have you seen the new tesla truck? its exactly what you are describing and big companies are ordering them already, we will see changes soon
Because a rectangle maximizes interior volume. Also most semi cabs are aerodynamically optimized to some extent.
upgrade costs and shipping storage capacity being reduced.
my truck gets 5 mpg but is all steel.
Repairs. The cost of repairs.
Very good question
