Battery Power: Truth or Fiction

NO RATINGS
A battery powered car? Get serious, designers. In Southern Arizona, we go from full A/C on to Heater on, not in one season, but often daily depending on our personal driving hours. My car is an A/C on wheels! A battery powered car would be feasible here, where we routinely drive 75 miles RT to go shopping, if the battery were 1/10 the present cost & weight, 10-100x energy capacity, and as fast to charge as a session at the gas pump. There should be no massive premium over a similar size and capacity car with gas engine. I owned a 2002 Prius, which got 48 MPG at best when I drove very conservatively. But they forgot a trunk, so I traded it in for a Suzuki Aerio SX hatchback and it gets 28 MPG with the A/C full blast, maybe 30 when the weather is nominal. Second car, maybe for a tree-hugging wealthy dude willing to remember to plug it in every time it is parked. That is a nuisance no one in their right mind should accept. The present premium of a hybrid over a comparable gas engined car will buy you gas for decades. History will look back on the electrics bleeding the wealthy as medicine did to bleeding the ill. It just doesn't wash.
