I am often amazed at the claims that so-called experts make, even in a court of law. For example, the government of Ontario recently defended its policy that Sikhs riding motorcycles should wear helmets (not a requirement in BC or Manitoba) by claming that turbans would unravel in the breeze, thus posing a risk to other motorists.

Born to be wild

… the Crown declared that an expert it had hired proved that turbans unravel rapidly in 100 km/h winds. The Crown’s test had been carried out by a professional engineer who purchased a mannequin head, mounted it on a stick and then placed the assemblage in a wind tunnel. [Link]

Say what? Turbans unravel at 60 mph? Have they ever seen a Sardar riding a motorcycle? Or riding a roller coaster? Or even sticking his head out of a moving vehicle? The paag stays on tight my friend.

To test this claim, the plaintiff, Baljinder Badesha of Brampton (can you say that 10 times fast?), tried to replicate the study. He drove down the Cayuga Speedway at … gasp, 110 kmh. Did his turban unravel and flutter into the wind like a wayward plastic bag? Ummm … no. It was fit to be tied.

Mr. Hutchison [Baljinder Singh’s lawyer] was unable to find a documented case anywhere in the world where a Sikh motorcyclist’s turban had unravelled. Skeptical, he persuaded the OHRC to authorize its own test. After he confronted the Crown with the dramatically different test result, prosecutors conceded that their engineer had grossly miscalculated the force of the wind he had generated to batter the imitation head, Mr. Hutchison said.

In fact, the device had been subjected to a 300 km/h wind. [Link]

That’s right - they used 180 mph winds in their test, more of a gale than the stiff breeze you get at 60mph. And even so, I’m not entirely convinced. I’ll bet if they used a real person with a real turban going 180 mph, it might still stay on. But in any case, given that driving at 300 kmh is illegal, the point is moot.

So now the Crown is switching arguments. Instead of defending this policy in terms of the danger to others that turbans pose (those huge swooping turbans flying around the freeway, covering up windshields!) they’re arguing that helmetless motorcycle riders will cost the taxpayers more:

… its main argument is now based on increased costs to the health system, should helmetless Sikh motorcycle riders end up suffering head injuries. [Link]

The problem is that if you accept this argument, why are they allowing anybody to ride on a motorcycle at all, given that it’s far riskier than driving a car. In fact, they should only allow people to drive safe, slow, sober sedans like the Ambassador.

…a study … concluded that, assuming half of all Sikh motorcyclists wear turbans, the increase in serious injuries would be between .43 and 2.83 Sikh riders a year.

The study also projected that medical treatment for traumatic brain injuries would … [lead to] a .00005-per-cent overall increase in the province’s annual health-care budget.

Mr. Hutchison told the court that the province already licenses motorcycle riders in spite of the fact that they have far more accidents than automobile drivers. “Clearly, the decision to allow motorcycles to be used at all recognizes and accepts a significant degree of risk and concomitant social cost,” he said. [Link]

I realize that Canada is not a very libertarian country, but where they draw the line between acceptable risk (riding a motorcycle vs. riding in a car) and unacceptable risk (riding a motorcycle with a turban vs. riding a motorcycle with a helmet) is clearly determined by social preferences rather than public health. You can’t be penny wise and pound foolish and then say you’re acting out of frugality, it wont wash.
