Yes,but........................................... .................................................. ....
A foil large enough to produce usable thrust would pose a stability threat at high speed.
In the late 1970s,Professor Alberto Morelli found that the 'fins' could be placed low,behind the rear wheels,controlling the center of pressure for stability,as well as acting like a wheel fairing,cutting drag.

A sail large enough to move a very small cabin.



Luigi Colani also under-slung the tail fins.



1-minute cross-post. Look to your edge radiuses.

This Arrivett Brothers' streamlined dragster of 1987 boasted a lower drag in yaw,than in straight-on flow.It's one of very few cars ever analyzed.

If you have the wealth to pursue it (and I'm talking hundreds of thousands of dollars),you could look into it.But there is no extant off-the-shelf technology which exists that can give you what you want.

Ok, last off topic post here, sorry.

The "legal fiduciary responsibility to maximize shareholder profit" thing seems to have been made up in the 1970's, and doesn't really exist:

It's genesis probably originates from the Code of Hammurabi,1754 BC,concerning damage to property while left in the care of another.
I liked Lynn Stout's article.Thanks.
Some modern day messengers liken most CEOs to psychopaths,with no concerns beyond profits.And corporations consider that there is a shortage of psychopaths in the market,which explains their high pay (demand-pull inflation).
Around 2010,'compliance vehicles' made up a population of 700,000, in a fleet of 240,000,000 U.S. light vehicles.
If certain beneficial things are to happen,these kinds of statistics will need to stood on their head.
I applaud any affordable EV,regardless of stripe.I'd like to live long enough to see hundreds of millions of them.
My brother lives close to Fernley,NV where Elon has built his massive battery manufacturing facility.I hope to see it in September.
' appreciate your insights.
