Seriously, "OMG! Dead batteries! Heavy metals!" seems to be the
anti-hybrid FUD that has caught on most among the public.

I thought the Prius battery pack only lasted something like 5-10 years
or 100k miles?

The warranty is 8 years/100k miles. It is also not deep-cycled like
many other rechargeable battery applications; the computer tries to keep
it between about 25% and 75% state-of-charge. See

(and scroll _up_ for the series), or
uggc://wbua1701n.pbz/cevhf/cevhf-zvfpbaprcgvbaf.ugz
and scroll _down_ to "The battery-pack will have to be replaced." The
top level has some links to photos of Priuses that have 300,000+ miles
on the original battery pack.

Otherwise the energy costs of building a car (any car) dwarf the
savings afforded by the tech.

You can put an upper bound on how much energy it takes to build most
any new car; it is the largest number on the window sticker with an
"$" next to it. If some random car sells new for $20,000, gets 30 mpg,
and will easily last to 150,000 miles, it will burn 5,000 gallons of
gasoline to cover those miles. At $3 a gallon, that's $15,000 in gas.
If over three-quarters of the sticker price is energy costs, then steel
and union labor must both be free.
