Again, have you seen one of these before?
What you speak of is called a velomobile. I haven't seen one before, but velos are rare, even among
recumbent bicycle owners. If I remember right the best-selling velomobile in recent decades still only had around 80 copies built and sold, world-wide.
It is usually a trike with a body over it to protect the rider (mostly) from weather and wind resistance.
There are a bunch, and they generally cost $7500+. Most are carbon/kevlar bodies and ones costing over $10K are not unusual.

Recently one company began making roto-molded bodies for their trike.
AFAIK they were the first ones to use this method-

It is cheaper than typical composite body velomobiles, but it's still not cheap-- $6000 AUD = ~$6150 US dollars.
