Not much has changed
generally in how people get anywhere. Cars, trains, bikes, planes... the options are pretty similar to what they were 50 years ago. We've had some minor improvements in availability, cost, quality & such but it's basically the same choices. The resurgence of cycling is just different choices within the same set of constraints.
Technology doesn't progress at the same pace across all fields. Innovation in the transport of people had a solid run from (well, dating these things is always a little arbitrary) from the age of sail to around the 1960s and then seemed to have stopped. The age of sail promoted Europe's rapid modernisation and industrialization. They dug huge canal systems in some countries. They rolled out empire-grade railroad systems.
Before World war one, air travel meant novelty items like blimps and planes made from bicycles. By the 1960s we had modern airline systems, supersonic fighters that could still fight today...In the following 50 years, we've modernized and digitized what we already had in 1960 but it's not much cheaper, faster or more convenient.
That's why I like the focus on transport. Self driving cars are such a cool technology they get some eyes onto transport. Uber gives us a transport unicorn, which gets investor and founder eyes onto transport. Ideas like hyperloop and Marsone are floating around as inspiration. Hopefully, we're going into a period of progress again.
