There's more to it than that. It's an issue of existing infrastructure as well. Where would someone go to purchase enough vegetable oil to run their car? Can there be enough mass produced to power all the vehicles now using petroleum based products? There are no pumping stations. No vegetable oil pipelines. Who will make the investment to provide such things? Cars can run quite efficiently on propane as well, and in Phoenix there was a big push for this (even with virtually free cars provided at tax payer expense), but there are about 4 propane filling stations in the entire Phoenix metro area. Who wants to drive 20 miles to a filling station?

I am all for cleaner burning fuels. But nothing will come without some sort of side effect. The buzz about hydrogen sounds great. The exhaust is water vapor. However, I've read that there is a concern that in major metro areas there would be so much water vapor produced it would actually change weather patterns.
