Making an electric car is trivial. The big problem is that battery costs still cause the majority of the total vehicle cost. The e-golf is a perfect example of that. It's identical to the ICE version except it costs twice as much at the cost of significantly lower range. The 2017 version is still at the 30k price point but the range was upgraded to 185 miles. It will probably take another 3 years until we see a 300 mile version to eliminate range anxiety for the majority of the population and then it will take another 3-6 years for prices to go down.

The ICE vehicle manufacturers are waiting for battery costs to come down. They aren't short sighted. It's simple economics.
