Planetizen: : "Regardless of the energy source for cars in your community, the biggest mobility challenge in cities is about the massive amount of space that cars demand. Space to drive in, and space to park in. Space for cars even when the cars aren't using it - dedicated space for "potential cars." It's staggering really, how much of a city is set aside for cars, and how unwilling we often are to even share that space with other uses and users.
Electric cars do nothing to address this space issue."
