Electric cars are indeed much worse for the climate at production time than combustion cars likely will be throughout their entire lifetime.

But the this matters little, as the electric car is not made to be the perfect alternative, it is instead made to be the "weird in between solution" that we need to bring as many devices as possible to use a common power source and get people acquainted with the concept, before moving to the actual solution.

The next steps will be better battery technology because, let's face it, lithium gel batteries suck, and proper power sources.

In the end, I guess it's kind of a "chicken and egg" situation.
