“So we follow our noses. Our noses are going to be smashed up on the fascia board.
“So we will have an air cushion that inflates when we crash to protect us.
“Now that we can drive much faster and with less regard for others: we shall be all right.
“Don’t you think if we really cared about safety we could consider replacing the inflatable bag with a row of sharp spikes?”
This is not a serious proposal, you understand.
The “safety spikes” observation has had many authors over the past 60 years and has taken many forms. It is an illustration of paradoxes ranging from risk compensation to the “lemons problem” to “moral hazard” in insurance. The true first author may never be known.
Tullock’s Original Intuition
This story was told by Richard McKenzie in an EconLib remembrance 50 years after the events described:“I remember, as a young graduate student in the early 1970s, listening to several faculty members in the foyer discussing the case for regulating the internal safety of automobiles, then an emerging hot political topic. They were refining standard arguments regarding mandates for the installation of seatbelts, collapsible steering columns, padded dashes, and airbags, all proposed to save lives.
“Gordon emerged from his office on hearing the discussion and insisted: ‘You have it wrong! Interior safety features in cars will reduce the costs of accidents for drivers and encourage them to drive more recklessly, causing more pedestrian deaths. To reduce deaths, the government should require the installation of a dagger at the center of the steering wheel with its tip one inch from the driver’s chest. Who would take driving risks then?’”
“The analogy has been made (and there’s just enough truth to it to get you in trouble) that in buying some company with enormous amounts of debt, that it’s somewhat like driving a car down the road and placing a dagger on the steering wheel pointed at your heart. If you do that, you will be a better driver—that I can assure you. You will drive with unusual care. You also, someday, will hit a small pothole, or a piece of ice, and you will end up gasping. You will have fewer accidents, but when they come along, they’ll be fatal.”
In 2012, the “Tullock Spike” came up (though not by name) in a discussion of crop insurance. The idea was that subsidizing crop insurance effectively subsidizes the taking of excessive risk, and reduces the incentives to limit damages, for farmers.
“If we all had a dagger sticking out of our steering wheels,” Walters continued, “we’d be more careful [when driving]. But what if crop insurance removes that dagger? How would we drive then?”
But that is what you would expect. If speeds are suppressed, and safety equipment is improved, the risks of death and serious injury are lowered. The results should be increased selection of risky behavior by drivers, including close drafting and bumping. More recently, in February 2018, NASCAR switched from restrictor plates to the more precise and consistent “tapered spacers,” which have the same effect and the same “safety” rationale. The 2018 NASCAR “Cup Series” champion Joey Logano was just as clear about the likely effect:
“I totally expect to crash more cars [because of the spacers]. ... As cars are closer and drivers are more aggressive, a mistake will create a bigger crash. We can’t get away from it. ... You know how it is when you’re on the highway and they check up right in front of you. You can’t stop quick enough and you’re only going 70, you know? Try going 180. ... So I assume there will be more crashes. I assume we’re all going to tear more stuff up this year.”
If anybody at NASCAR were serious about wanting fewer wrecks, they’d put Tullock Spikes in steering columns, not little plates in carburetors.
