So what? This is 40 years after the first Man walked on the Moon and we are still all living on Earth. It's been about 60 years we have discovered the double-helix structure of the DNA and we still have yet to see revolutions in medical practice coming from it. What is your point, exactly ? There are clear reasons why no huge technology leaps take place at once. Most innovation is progressive, iterative and it is very likely that you will not see a drastic change of technology within your lifetime.
There is progress, but on the transportation front from a practical point of view the biggest one so far is the electric bicycle.
Certainly the top speed of either of those cars isn't practical, but the reason that the Veyron can go so much faster is that there have been massive improvements in automobile technology since the 60s, in just about every every way imaginable. Safety, efficiency, control, materials tech, aerodynamics, etc. That we still drive so slowly can be probably attributed to momentum in automotive laws and/or driver skill / lax license requirements. If we were willing to invest more in our roads and stop thinking of driving as a right instead of a privilege, we could be driving much faster today.
Also, above 100 Mph or so the aerodynamics change substantially. There is a clear cut-off point above you are definitely in 'no mistakes' territory, even ignoring a bit of cross wind as you come out from under an overpass get get you slammed into the guardrail or driven off the road.
Add to that ice, snow, rain, night conditions, glare, low sun and so on and pretty soon the driver (automated or not) is not the limiting factor but physics and getting reliable sensor inputs is.
Anything over 140 will probably not be practical for mainstream deployment, even in Germany where there are lots of skilled drivers and it isn't rare to see an old lady do 150 Km/h there is a sharp drop-off above that point reserved for those the possession of more money than brains. It simply isn't practical from a fuel consumption and safety point of view and even the safest cars are death traps at speeds beyond that.
See 'crashedexotics.com' for the end result of that route.
I think with the spread of autonomous driving technology we'll be able to see even more proper, and reasonably safe, speed from cars.
To say that only communication and shopping have been revolutionized in the past 20 years is grossly misinformed. Human interaction with each other, with ourselves, and with knowledge has been fundamentally changed for a very substantial portion of the population. No, it has not reached every corner of the globe, but neither has electricity, radio, or television.
And let me question your claims about knowledge being fundamentally changed. Kids still go to school. Still pass exams the same way as 50 years ago. Education has not changed at all, except for a pocket of people who follow coursera or other online systems. It's all very small and you are probably exaggerating the impact because you are aware of it and living in that particular tech-sphere. Not everyone read Hacker News, not everyone knows how to use computers, and most people who have computers do the same very basic things with them every single day. At least my claims are substantiated. Amazon has clearly changed shopping, and Skype/IM/email has drastically made communication cheap and led to calls being very affordable in almost every location in the world. For other things, change is not so visible and apparent.
Everyone. Because what changed is not only the amount of information, but also the immediacy of access to it. Those people going drinking to the bar quite likely found it on Google before going there for the first time. And those same people now Google up everything they want to know the moment they need it, including many practical things. "Normal" (non-tech) people, from my observation, tend to look up on-line many things in their life, for example gift ideas, travel & tourism information and practicalities ("how to do X").
You could also argue that it is the first time so many people are exposed to such a big amount of cultural work - including pirated movies, music, YouTube and Internet memes. People share common culture across the globe, and the Internet itself slowly starts to behave like a single brain.
