"Now we just have to convince several million other drivers."

So far I'm claiming two close colleagues at work (both of whom purchased HCHs) and one other friend (who purchased a Prius) among those whom I have significantly helped convince. And one other is definitely in the queue.

One bite at a time, I guess that's how we have to eat this elephant. (Although that analogy has never worked for me, having never eaten any elephant, at least not that I'm aware of).
