While researching I found this particular image, I picked it out because it seemed quite unique compared to the other predicted technologies.
I think this image is quite outlandish, even for the current retrofuturistic art. Although it seems to be set in the 19th century, the device seems to take inspiration from a train or bus. However it does stay true victorian retrofuture art in that the vehicle has wings that, as you can see from the second picture below, was a very popular view of future technologies in victorian times.
It is obvious that the majority of these images were made by optimistic artists, as you can tell the designs were quite ridiculous, even at the time the images would be seen as outlandish.
I will continue to focus more on the 19th century and their view of a future with wings and tesla technology.
