Battery Packs other costs etc..
The long term residuals of Electric/Hybrid vehicles is still uncertain. Hybrid's especially, with their inherently complex mix of electrical and combustion power, and the myriad of sensors - I would fear for the longer term reliability and costs of running these, when a mechanic open's the lid, looks in the engine and does not know why your 5 year old Prius is a bag of sh1te and won't go, or the dash is lit up like a Christmas tree
The questionable lease/swap options/costs of some of the battery pack units is also a worry. They are phenomenally expensive parts to replace.
The Euro $8/gallon is a huge concern, but this has positively driven the market towards a huge reduction in oil consumption with much more economical cars, and the widespread use of diesel in cars/vans/SUV's - leading average gas mileage to be heading towards 40 miles per gallon, whereas in the US this is terrible - What 20mpg avaerage and in your must have v8 SUV 10mpg ?.
