I was reading Wendell Cox's recent attack on the Center for Neighborhood Technology's affordability calculations, and was struck by one thing he wrote:"transportation costs will be reduced in the future by the
far more fuel efficient vehicles being required by Washington."*
In other words, don't worry about Americans being impoverished by the cost of a car for every man, woman, and 16-year old in the House: the technological miracle of fuel efficiency will save us.
Now, this argument has a grain of truth: new EPA regulations will require the average vehicle to get 35 miles per gallon by 2016**, so cars will become somewhat more fuel efficient if next year's Republican Congress or the federal courts don't get in the way. But even so, the benefits of fuel efficiency may be canceled out by gasoline price rises - and even if they don't, gasoline costs comprise only about 30 percent of vehicle-related expenses. In 2007 the average household spent $2384 on gasoline and motor oil, $3244 on car purchases, and $2592 on other vehicle-related expenses.***
I have seen the same argument raised to deflate concerns about automobile-related air pollution or greenhouse gas emissions: even if pollution is a problem today, tomorrow's Wonder Cars of the Future will drive the problem away. For example, one blog writes: "The widespread availability of electric cars will make one argument made
by transit proponents harder to advance: that riding trains and buses
is better for the environment."*****
But it is not just the defenders of the sprawl status quo who rely on hoped-for technological change to support their views.
Critics of sprawl often argue that sprawl is doomed because of Peak Oil. According to this argument, supplies of oil will become unreliable, and the Peak Oil Fairy will slay the dragons of unsustainable development. One recently published book summarizes the theory: "Why Your World Is About To Get A Whole Lot Smaller."
To be fair, one or both of these arguments could be true. It is possible that 100 mile-per-gallon cars will revolutionize American transportion. It is also possible that scarce or expensive gasoline could revolutionize American transportation.
But maybe not -and it seems to me that a technological change that hasn't happened yet isn't a particularly strong argument for any public policy.

Hybrid Car Sales Fail to Meet Predictions
Over a decade ago, automakers predicted that every new car would be a hybrid by 2020. Why were they so off the mark?
Electric Cars: What Are You Waiting For?
Electric cars aren't as expensive as they once were, and the cost of ownership has always been low—so what are you waiting for?
Electric Cars Hit the Million Mark
The worldwide stock of electric cars hit an impressive, if still superficial, milestone in 2015: one million electric cars currently on the road around the world.
Opinion: Aging Population, Declining Fertility Requires Long-Term Investments
Faced with the dire consequences of a one-two punch of aging populations and declining birthrates, one writer has suggestions for how policy can help ensure a better future.
The Surprising Oil Tax in the Inflation Reduction Act
President Biden has made reducing gas prices paramount in his administration, so it was likely a surprise to hear a Republican senator last Sunday warn TV viewers that a revived and increased oil fee in the climate bill will increase their gas costs.
The Tide Has Turned Against Open Streets
Once a promising development for advocates pushing for a less car-centric future in cities, the open streets movement has ceded significant ground to cars since the height of the pandemic.
Opinion: Los Angeles Transportation Plan Will Increase Driving
L.A. Metro’s plan to add hundreds of miles of new traffic lanes is projected to increase carbon emissions by 10 million metric tons.
How Extreme Weather Threatens Transit Systems
As weather events become more intense and unpredictable, transit agencies must take steps to protect their aging infrastructure from flooding, storms, and extreme heat.
Federal Rule Would Require Regional Emissions Reduction Targets
A rule shelved during the Trump administration would require states and metropolitan areas to set targets for reducing tailpipe emissions, but advocates say it doesn’t go far enough to mandate results.
