When you carry the Internet in your pocket there is no turning back and it makes no sense to use a ton and a half to move 75kg.
I have a year with a android from EOI in my pocket and I will never again live without a mobile device connected to the Internet, but neither will you. disruptive innovation and you will soon see it as something natural, in fact, the phone function of your cell phone will be secondary or rather, it will be one of the ten main functions for which you use your device.
Mobile Internet is a revolution because it means a different user experience from the one we are used to, for about five years we have been talking about the convergence between the mobile and the PC; I have no idea where it will be standardized, personally I think that the 7' touch screens like the Samsung we are going to give this year to the students of the School are very practical but it will be a long time before we see a standard and maybe it will come from Apple, Microsoft or Google. What I am sure of is that Internet in your pocket will triumph as the bidirectional Internet or 2.0 has already triumphed.
I recognize myself as a bicycle freak, in fact, the one in the picture is my Amaro Rosellini so you should take my subsequent statements with care. Just as the near future of the Internet is mobile, I believe that the future of daily mobility is personal, i.e. with personal vehicles; I suppose they won't be fixed-gear bikes and maybe not even bicycles, but the current situation is unsustainable. On average, our personal mobility is based on getting into a one-and-a-half tonne jalopy (see car) to do ten kilometers in which we move our 75kg of weight; it is not my case but I average with the ladies of the Barrio de Salamanca who take their fifty kilos to breakfast on the three tons of an Audi Q7. The traffic jams in the cities are insufferable, we are eating up fossil fuels and we are messing up our environment.
That the bike has a huge future is not something that I think or want, but it is something that the venture capitalists already think, and if not look at the purchases of bike brands that took place between 2007 and 2009; or those of Ikea and Apple to get headlong into a market that is not theirs. That it is also the solution to many of our ills, is not my idea but that of cardiologists, psychologists, endocrinologists,... That the bicycle is about to experience a boom like the one it experienced in the late nineteenth century and became the quarry of the aeronautical industry... you only have to see the amount of innovations that are occurring in the sector. That the bicycle is the future of urban mobility,... well, you only have to look at thirty or fifty-year prospective studies of cities like Seattle and New York that place the bicycle and intermodality of transport as the keys to the medium and long term.
As I do not know at what point this urban mobility should be standardized, I propose the creation in cities of three types of roads, namely: slow, medium and fast. The slow ones would be universal, that is, any street would have them; the medium ones would be in the majority, that is, most of the streets would have them and the fast ones would be in half of the roads. The slow ones would be for walking, running or slowly in a vehicle (less than 20km/hour), the medium ones would be for going between 15km/hour and 30km/hour and the fast ones between 25km/hour and 60km/hour.
