Wait until we have millions of hybrid vehicles on the road and have a few involved in accidents. Imagine passengers or more likely rescuers being electrocuted or having an accident that ruptures the trunk load of batteries creating a major hazardous spill. We already have a serious pollution problem from MTBE that government clean air policies mandated be added to gasoline.
Fear nothing more than the government trying to fix things.
Look, I hate to add fuel to the fire, but those EnviroWhackos were the ones that made us put that alphabet-soup attitive in our gas (HTML? BTHM?) and it turns out THAT is seeping into the water table and is worse for you than airborn pollution.
We need to declare a "Manhatten Project" on fusion power, DUMP money into it, and tell the A-rabs to go pound sand. (And a bio-engineered bug that eats THEIR oil, would be good as well.)
