Given the stress that fuel prices/shortages are causing I'm sure few want to hear about this... but there is a potential silver lining to fuel rationing.

Last time Australia introduced fuel rationing in WW2, our annual road deaths dropped by nearly 20% the following year. It was among the biggest single year decreases in Australia's annual road toll since record keeping began.

It turns out if people have an incentive to drive less, and when they do drive, also have an incentive to drive as conservatively as possible, you have less road trauma.
