I agree, unless they can come up with a good/efficient way of "pumping" NG into our tanks. Compressing NG means you loose some of the net efficiency.
Honda, and likely others, already sell vehicles that run on natural gas. There are also companies already that can perform the conversion (some specialize in GM etc).
Honda can provide a home pump that uses your existing natural gas lines.
I don't see NG vehicles as the "silver bullet" cure, but of several things I'd like to see explored ASAP.
IMO, just because we can't solve the problem in one blow doesn't mean we shouldn't start nicking away at it as much as possible now.
Likely some solutions are a better fit for some, others have different needs. E.g., I drive less than 10 miles a day, so I don't really need the long trip capabilities others do. From what I can tell, NG vehicles can go about +200 miles before a fill up is required.
Edit: Given how price sensitive oil seems to be, a rather minor reduction is demand could potentially have a pretty big price effect. With tax credits etc, moving a relatively minor percentage of our commuting population off oil/gas and onto NG and electricity could have a significant benefit.

Yes, I am very aware of CNG vehicles. I worked for a company that had a small fleet of them. The problem comes in with the compressor. A 4-stage+ compressor is needed to get the required PSI and this requires quite a bit of Electrical power(not to mention 480V 3ph for best efficiency)...or would take a very long time(115/230V) and be considerably less efficient.
But sure, it could have some positive effects but it has quite a few problems - namely infrastructure. The place I worked had a 30 mile radius they ran their trucks. Run out of fuel and you are screwed...
