It’s April 15. If you bought an electric car in 2013, you can claim a tax break today. If you bought a plug-in hybrid, you can get a tax break today. But if you don’t own a car and walk to work instead? Sorry, Charlie.

Last year, while the House flailed in partisan misery, the Senate passed a transportation bill 74 to 22. When the bill was signed into law, it was considered one of the few real achievements of a deeply divided Congress. Environment and Public Works Committee Chair Barbara Boxer got tremendous credit for enacting legislation three years in the making. And yet, it left a lot of good provisions on the cutting-room floor. While MAP-21 included some modest reforms, lawmakers missed an opportunity to prioritize transit, biking, and walking -- modes that are gaining popularity and help achieve national goals like congestion mitigation and air quality improvement.

Quick quiz: What city is the world leader in highway teardowns? San Francisco? Portland? Madrid?

Jeff and I had a great time this week, getting all outraged at the short-sighted move by the Tennessee Senate to ban dedicated lanes for transit, and high and mighty about cities that devote too much space to surface parking at the expense of just about everything else. And then we treat ourselves to a fun conversation about the origin of the American playground -- and whether the entire city should be the playground.

It was a dark and stormy day in San Francisco and Jeff Wood stayed dry in Woonerf studios, recording the Talking Headways podcast with co-host Tanya Snyder, who was bitter that days after the spring equinox, Washington, DC, was getting hit with another snowstorm.

Here's the rosy scenario of a future where cars drive themselves: Instead of owning cars, people will summon autonomous vehicles, hop in, and head to their destination. With fewer cars to be stored, parking lots and garages will give way to development, eventually bringing down the cost of housing in tight markets through increased supply. Pressure to expand roads will ease, as vehicle-to-vehicle technology allows more cars to use the same road space. Traffic violence will become a thing of the past as vehicles communicate instantly with each other and the world around them.

Quick quiz: Are you a left-brained cycling advocate or a right-brained cycling advocate? Here's how to find out: If someone asks why you ride, do you talk about the wind in your hair and the sense of satisfaction achieved by pedaling up a hill? If so, you're doing it wrong. If you want to sell your bike project to funders -- like, for instance, U.S. DOT -- you’re going to need to left-brain it all the way. Here’s how.

So transit ridership is up. Everybody knows that. It’s at its highest point since 1956. Right?

How embarrassing. The Republican National Committee’s outreach to young potential voters misses the mark so badly they're just proving the point they were hoping to disprove: The party is absolutely clueless about young people.

You think the conflict between Uber and regular taxi drivers -- and cities like Seattle -- is bad? Check out how new taxi apps in China are upending the transportation system and central economic planning. Meanwhile, in Houston, a flea market has brought revitalization without gentrification to a depressed area near the airport, and now an urban design firm is bringing in pop-up infrastructure like mobile libraries and grocery stores, along with sidewalks and bikeways. And Californians are proving that the culture shift away from the automobile and toward other modes of transportation is happening -- maybe even faster than we'd thought.
