Any different bike costs are just crazy. A recumbent bike isn't that different from a regular bike, but costs far more for equivalent quality. Any velomobile-like vehicle is going to be niche and costly. Good luck, but I don't think you're going to find an inexpensive option unless you can find someone selling a used one.
Have you searched for a "surrey"? Maybe you'll have better luck with that?
Maybe add “fringe” to the search
idk that you're going to find much that isn't thousands of dollars. Have you considered something with a trailer instead?
Check your local law:
many jurisdictions label more-than-3-wheels as "motorcycles", even with no motor on 'em, because that allows them to abuse the population's potential.
Think how much use a 4-wheel bicycle-car could be, in event of no-available-fuel, to a farmer:
they could get stuff to the local market, instead of throwing it away.
Or, if a dairy farmer, they could get emergency-people to their farm, to help, instead of just killing their entire herd.
Bureaucratic-authority won't tolerate autonomy.
They'll NEVER allow the law to be based on something sane, like whether it's a human-powered-vehicle, instead of the idiotic "number of wheels it has", law.
Integrity in legislation is faaar too much to ask, of legislators.
Ask that state which reinstated an anti-abortion law from the 1800's, if integrity ought be permitted to interfere with their authority..
Look up "Rhodes Car" & see that what you want is already made, or was, anyways ( iirc, they used to advertise in the back of Popular Science? )
I got the name wrong, so here's a wp link:
The link in that article is the same as the one I posted. Trying to determine if there are other options.

It's a little sad that we need to actually say this, but:
Don't be an asshole or you will be permanently banned.
Respectful debate is totally OK, criticizing a product is fine, but being verbally abusive will not be tolerated.
Focus on discussing the idea, not attacking the person.
