Fewer injury crashes after Tampa police stop ticketing cyclists

TL;DR summary: Injury bicycle crashes dropped 19 percent after Tampa police stopped writing tickets to scofflaw cyclists when a newspaper investigation revealed possible racial bias in the department’s targeted enforcement.

Bike school: Should people on bikes be required to use bike paths?

Trees down on San Tomas Aquino Trail Santa Clara California

Happy Friday, all. I occasionally participate in the weekly BikeSchool Twitter conversation that takes place every Thursday night beginning at 6 P.M. California time. A “professor” asks a series of questions to generate discussion on bike-related topics.

Last night’s guest professor, Matthew Dyrdahl, is the Bicycle & Pedestrian Coordinator for the city of Minneapolis, MN. Among his many good conservation starters, he asked if people “should” use a path next to a road if it’s available.

Radio Re-run: Freakonomics on Traffic Safety

KQED Public Radio in San Francisco replayed the May 1, 2014 edition of Freakonomics Radio, titled “The Perfect Crime.”

The show begins with a discussion of homicide by car. You’ve heard or seen this claim before both here and elsewhere: If you want to kill somebody and get away with it, run them over with a car.

Walking in San Francisco

This is a lead in, however, to the issue of pedestrian fatalities both in New York City and nationwide. The show moves the focus to the issues traffic safety experts have beaten the drum on for a few decades. From the transcript of the show:

DUBNER: Okay, so that is a massive improvement, to be sure. How did this happen? How did pedestrian deaths fall so much?

NOLAND: The policy that we followed on trying to save pedestrians is to stick them in cars, so they are no longer pedestrians. And that will reduce your pedestrian fatalities ‘cause you don’t have as many anymore.

DUBNER: Robert Noland is director of the Voorhees Transportation Center at Rutgers. He says that as the automobile rose to exalted status in America, the roads – and the entire landscape really – were built to privilege them, the cars. This is most pronounced in the parts of the country with high pedestrian and bicyclist deaths, like the Southeast.

NOLAND: They focus very much on traffic flow and making the roads wider, straighter, and faster. With the assumption that that’s safer. And what a lot of the guidelines do is they look at freeways, which are very safe, and they’re safe because it’s controlled access. You don’t have any intersections. And they take those sorts of design guidelines and they apply it to a city, to city streets or suburban streets and create these very large arterial roads, which tend to be the most dangerous roads whether for drivers or for pedestrians.

I’ve summarized some highlights of the show below, but the show itself is a good introduction to the traffic safety topics I like to focus on. Invest a half hour listening online, or you can read the transcript here.

The show is about pedestrian safety on public roads, but many of the same issues apply to those who ride bicycles.

  • The American legal system makes vehicular manslaughter prosecution very difficult because “It’s just an accident.”
  • About 4,000 pedestrians lose their lives annually to auto traffic. Any other consumer product that killed 4,000 people annually would result in outrage and action.
  • “Distracted” walking, jaywalking, etc: If a pedestrian does something wrong, does he or she really deserve to die?
  • The dehumanization of anybody who doesn’t drive a car. The only people who matter are people who drive autos.
  • We don’t really know who’s at fault because the only witness is the surviving driver. Responding officer hears only one side of the story. See also Single Witness Suicide Swerve.
  • Oh that poor, traumatized, innocent driver who was just minding her own business when *wham* that pedestrian came out of nowhere to ruin her day!
  • “We reduce pedestrian fatalities by putting them in cars. The pedestrian fatality rate has fallen because we don’t have as many pedestrians anymore.” Get off the road!
  • Areas with high pedestrian and cyclist deaths “focus on improving traffic flow by making the roads wider, straight, and faster with the assumption that it’s safer. They apply Interstate freeway design guidelines — which are very safe because they are controlled access — and apply them to city streets and suburban streets. They create these arterial roads which turn out to be the most dangerous roads both for drivers and pedestrians.” Listen up, Santa Clara County Roads Department!
  • People don’t ask who roads are designed for. “People don’t ask it because we think we know what roads are designed for. It’s for cars, of course.” But if you ask people 100 years ago what streets are for, you’d hear different answers. None of them would have said streets are for cars, although there were a lot of cars then.
  • Facilities designed for bikes and pedestrians in Europe are not “just random actions” but a deliberate result of policies.
  • Europeans put an equal or even greater emphasis in their street design and policies on bike safety and public transit than on automobile transportation.
  • Europeans are not bashful at trying innovative strategies to improve pedestrian and bike safety. American traffic engineers are much more conservative.
  • Heavy media coverage of fatalities from freak occurrences followed up by demands to improve safety, but little mention of the 4,000 pedestrians killed annually by cars in the USA and no similar outrage to improve pedestrian safety. Why is that cost in lives so accepted?
  • “If we had 4000 people die each year in airplane crashes, something would be done.”

The River with No Bridge

The rain this past weekend in the San Francisco Bay Area reminds me of the modern Japanese classic “The River with No Bridges.”

A revenue neutral carbon tax for California?

What if you could make driving dramatically more expensive in a way that won’t punish people who drive, but reward those who seek ways to reduce their driving without wrecking the economy?

Gas tax and Santa Cruz

Thirty years ago, conservative columnist Charles Krauthammer proposed a what he called the “Net Zero Gas Tax to reduce consumption. To keep revenue neutral, he tied his proposed gas tax increases to a dramatic reduction in the payroll tax equal to the average tax paid nationwide.

For example, if the average American contributes $4000 annually toward’s Krauthammer’s dramatically higher gas tax (on the order of a dollar per gallon), then every taxpayer gets a $4000 tax rebate.

Good morning from America. I love the diversity of Americans who ride bicycles in the San Francisco Bay Area of California.


We make America great by paying more than our share in taxes to support transportation infrastructure and subsidize those drive. We take up under ten square feet of road and parking space vs over 100 square feet required for each and every car. The inconvenience we cause to other road users is inconsequential when compared to the gridlock caused by thousands of space hogging motor vehicles. We rarely kill or maim others, while motorists kill somebody directly every three hours. We don’t contribute to killing smog, and help keep fuel prices lower by leaving more for others to use. We do all this with minimal wear and tear to roads, driveways and parking lots, since the damage caused by each bicycle is less than 1 part in 40,000 compared to the damage done by a medium car.


Is it too much to ask for the Powers That Be to occasionally throw us a bone?
