I guess Toyota eventually changed the battery design away from giant AA cels. (Though it might be fun to actually make one of these and stick it on your car...)
Back in the 1970's Exxon had a slogan "Put a tiger in your tank" and they used to have these tiger tails that you could clip onto your gas cap. You could do something similar on the Prime with a short piece of electric extension cable. Of course only as a gag while you are driving, you wouldn't leave it in a parking lot like this or someone would mess with it. And I guess you would have to put up with a "Fuel door open" message
