Hybrid car pioneer and “father of the Prius” Takeshi Uchiyamada says the billions poured into developing battery electric vehicles have ultimately been in vain. "Because of its shortcomings--driving range, cost and recharging time--the electric vehicle is not a viable replacement for most conventional cars," said Uchiyamada. "We need something entirely new." Uchiyamada’s comments come as the U.S. Department of Energy announced Thursday that the government is backing off President Barack Obama’s promise to put one million electric cars on American roads by 2015. As Breitbart News reported last September, there are just 30,000 electric cars on American roads.
