If the Prius does it for you, then that's nice. But please don't think they're a solution for everyone.

Last time I drove one I found it painfully slow, poor handling and disappointingly thirsty (i.e. sub 50mpg). In short, I hated the damn thing.

For my usual driving (which doesn't involve sitting nose-to-tail in endless traffic jams), existing diesels do the job cheaper, quicker and with less effort.

Having said that, I rarely drive > 250 miles, so put me down for a lottery win and a Tesla! :-)
