I would Really like to see the driverless-car weenies focus on just expressways first. There, we have a controlled environment, more like the corporate parking lots in Japan where robot busses are as normal as elevators. To get into the HOV lane, you just need a vehicle equipped maintain negligible clearance in a non-contact "train" of other traffic. Once there, you could punch in your exit, and get back to screen time.

The downforce comes because the fan pulls airflow up into the tall diverters, and acts forward of the rear axle line. As compared to airfoils at the front and back that have to be balanced.

The shape is virtually identical to the F1. The two-tone disguises it somewhat. It's the same size on the outside but bigger inside.

*Now I want to see a boxer four rear engine with a Porsche fan that blows, instead of sucking, right out the back like the T50. The difference would be it would be on all the time.
Long but good video.

Thank you for posting it.

That an obvious 'avenue', but I would Really like to see an adversarial generative AI applied to rock crawling.

What I notice is the continuous chamfer along the upper edge. Much like the Cybertruck nose. It seems to be a design language that extends through the truck proposal. The window sections above the doors flip open.

Also the the jump seat on a suicide door.
Interesting video and vehicle.

Some news on that design.

I was more interested in the Sky-Pal, but there is nothing about it in my-search-engine-of-choice. The Flymobile has two references. One is just the picture. The other says

Yet it appears in Trailer News in an ad. Wikipedia lists it as an unbuilt two-seat monoplane. I like the Indian motorcycle fenders.
Found using search phrase "Curtiss Wright pusher twin boom". See post #50 in link below.

Curtis Wright 21 [NX37601]

CW-21 aka 21 1947 = 4pCmwM; 125hp Lycoming O-290 pusher. Podlike fuselage with twin booms and twin tails; tricycle gear. POP: 1 [NX37601].
I agree, very nice but perhaps had cooling issues? Just a guess, have not researched but could have been a military design looking for new life in civilian world as Sky-Pal.

Curtis not Curtiss, see link different company.

More cool pushers in link below.
https://www.reddit.com/r/WeirdWings/..._multipurpose/

Only currently known source of Curtis, just above Custer.

They certainly reduced the frontal area, I think you need an aerodynamic face and hairstyle though.

That looks like it even avoided the problem of the back end getting light at speed. Was it ever raced?
