The current state of gas prices may not be as big of a ball-buster for Prius owners, but recent reports suggest that there aren't as many Priuses on the road as there could be because of manufacturing shortages. One move by Toyota to try and combat this shortage is by building a $192 million battery plant in the Japan city of Shizuoka. Toyota is partnering with Matsushita Electric Industrial Co. for a plant that will produce nickel-metal hydride batteries, the same batteries used in the Prius hybrid. Maybe they'd save on materials if they made smaller keys. [Wired] (Image via Getty)
