They've essentially abdicated responsibility for fuel economy to the automakers.

Ford is at the bottom of the barrel among major auto makers on fuel economy, but today is a better day. Increasing hybrid production is a good step in the right direction.

As soon as you implement a strong, fixed target for reducing oil use, stricter fuel standards will inevitably come into play. Incentives alone won't do the trick.

Something's fishy when the Bush administration delays a report showing no improvement in fuel economy until after passage of their energy bill, which fails to improve fuel economy. It's disturbing that despite high gas prices, an oil war and growing concern about global warming pollution, most automakers are failing to improve fuel economy.

Americans are notorious for ignoring fuel economy. I think that's going to change.

Converting to fuel ethanol will not require a big change in the economy. We are already ethanol-ready. If ethanol were available on the supply side, the demand is there.
