A large-scale introduction of electric cars faces many technological hurdles and promises to be time-consuming and expensive.
Greening public transportation and cargo traffic, on the other hand, could be done fast with existing technology for a reasonable price - if we opt for the trolleybus and the trolleytruck.

The electric car is not a technology of the future, but from the past.
The electric car is 170 years old. This may sound surprising, but e-cars predate automobiles with a combustion engine. They were driven out of the market in the beginning of the 20th century because petrol engines had significantly better mileage. One century later, the electric car still faces the same – fundamental – problems. Furthermore, the need for batteries makes them eco-unfriendly by nature. The only possible green future for electric cars is a wired future: hooked up to the overhead lines, like trolleybuses and bumper cars.

From the earliest civilisations right up to the start of the Industrial Revolution, humans used sheer muscle power, organisation skills and ingenious mechanics to lift weights that would be impossible to handle by most power cranes in operation today.
We don't need better batteries, we need better cars.
