In reality though, they are a long ways from being widely available. Why? Sometimes it's because the technology will take a long time to develop (an electrically powered car like GM's Chevy Volt). Other times it's because the widespread customer base is slow to embrace the new technology (hybrids) so the offerings are limited.
Which brings us back to trying to get more out of our standard internal combustion engine. GM and others are making progress. And for now, that's what we'll have to accept as we wait for the newer technologies to be built or more widely available.
