As U.K. Telegraph reports, "cars will be banned from London and all other cities across Europe under a draconian EU master plan to cut CO2 emissions by 60 per cent over the next 40 years".
Once public right (at least in the cities) to move around independently is taken away, then it becomes easier than herding a flock of sheep to manipulate the masses.
Why do you think the left here has long been pushing for hair-brained ideas like rapid rail, etc. despite geographic and cultural reasons that render them worthless? The answer is the same whether you are talking about transportation, single-payer healthcare, energy usage, or a myriad of other areas: CONTROL OVER POPULATION.
That is Totalitarianism 101 for those not familiar with Lenin.
