Will cars ever be replaced in the future,same way they replaced horses?

It could be a better machine, which can be improved in several ways, including adding flying capabilities for trading roadways for airways (cheaper and much more space) or going directly to your home in a tensegrity sphere [1], or aquatic vehicles for communities in the ocean (greatly expanding living spaces available as well).

But I think one of the major shifts was from using a living creature to using a machine. Perhaps, with advances in bio-engineering, it could go the other way? Perhaps we could design very efficient animals for transport, including flying, that would double as family pets? And instead of using petrol or chemicals for fuel, you could just feed them the leftovers from your family meals. Thus, it would help reduce food waste, have easy to obtain fuel, and provide a ready-made friend for the lonely.

Here is an idea: https://youtu.be/Pv5JQnmD1Yk

In one way of looking at it, a horse and a car are the same thing: low energy and low complexity for high flexibility and maximum speed ground transport.

As energy and flight tech become cheap enough, with no exhaust blast, small footprint, highly maneuverable, etc., they will supplant wheeled vehicles for shorter and shorter trips.

Alternate transport tech also plays a role, such as Trantor-style moving sidewalks in densely populated places, etc.

I keep waiting for something like skyTran[0] or Hyperloop, but I don't know if it's just vapor.

Trams won't replace cars but they could help reduce car trips and reduce the number of cars on the roads.

Trams may sound old-fashioned, but this mode of transport is in fact more attractive today than it's ever been.

However, cost and construction time is a major hurdle to introducing trams. Tram infrastructure is expensive.

There is a cheaper, hybrid alternative called the trolleybus. It's a bus that runs on electric overhead lines so no need for tracks in the road like a tram.

Examples of the trolleybus can be found all over the world. But in many countries they fell out of favour and were scrapped.

While the trolleybus has it's disadvantages (the visual clutter of overhead lines being just one of them), maybe it also deserves a fresh appraisal?
