^The wheels on Kirk's motorcycle had no spokes. Whatever was holding the tires onto the bike was invisible, perhaps some kind of forcefield. Not really that different from a hoverbike, and it may have some advantages over a hoverbike, like maybe traction.
Or maybe it's just an indulgence. When the technology is advanced enough to allow just about anything, it's reasonable to expect designs that are motivated more by being cool than being practical. Why would a hover-technology bike have wheels "hovering" on their axes? Well, why do people today customize their cars with spinning hubcaps or oversized wheels or that bizarre bouncing-suspension thing? Why do so many single people insist on buying obscenely huge SUVs? Why do stretch Hummer limos even exist? It's because they can.
As for a source of gasoline, there are already nascent technologies that can make petroleum from plastic waste. A technology centuries ahead of ours wouldn't be limited to existing geological sources. And even today it would be possible to refit a Corvette with a diesel engine and run it on used cooking oil. Surely they still use cooking oil in the 23rd century.
"Not know what gasoline is?" That makes no sense. We have electric lights, but there are still candlemakers. We have cars, but there are still people who make horse-drawn vehicles for specialty use, or who rely on them as a matter of choice like the Amish. For that matter, there are still people around the world who still live pretty much as their ancestors did thousands of years ago. Humanity does not advance in lockstep. Today, the most advanced technology coexists alongside populations that live by traditional subsistence agriculture, horticulture, even hunting and gathering. Millions of people still live according to techniques and technologies as they existed thousands of years ago. They may carry cell phones and laptops, but they still use traditional methods to build their homes and raise their food and so forth. So there's no reason to assume that humanity would ever completely lose or forget the knowledge of its past.
And lots of people collect antiques of all sorts. This is news to you?
