It’s Economics, Stupid! Why Motorcycle Lane Filtering is Becoming More Accepted

No one likes commuting in traffic but if you have no choice but to face the morning and afternoon rush hour, there’s no better way to do so than on a motorcycle. Being maneuverable and small, a motorcycle can squeeze into the gaps separating cars and get to the front of the queue in a fraction of the time. Yet, unlike much of Europe, lane filtering is not only frowned upon in the United States, it’s a bookable offence virtually everywhere. There’s a change in the air though and the example is actually from a hemisphere away.

What is most bizarre is that the United States, a country which values personal freedom above virtually everything else and lets riders legally not wear a motorcycle helmet in 31 states (of those 28 states, you only have to wear a helmet if you’re 17 years or younger in most cases), only one state legally endorses filtering – California.  It defies all logic and common sense but that is the current status quo.

Yet in just the last few months, a country that has more onerous restrictions on personal freedoms, where helmets are mandatory 100 per cent of the time, where new riders are restricted to lower powered motorcycles for a number of years – two of the three most populous states in that country have legalized filtering – they being Queensland and New South Wales, Australia.

It’s the Economy, Stupid. The Real Reason Motorcycle Lane Filtering is Becoming More Accepted

So why have two states in Australia, representing nearly 50 per cent of the country’s population allowed filtering? This is a country that in a right wing American’s mind is probably a socialist utopia, what with all their universal healthcare and gun laws. The reason is economics – it’s all about money.

Australia, like almost every other western nation in the world has begun to tighten its belt. Money isn’t flowing as freely into government coffers as it once was, yet populations continue to grow and put pressure on infrastructure – especially roads. Like the United States, Australian governments love roads more so than public transport and years and years of road upgrades have done nothing to dent congestion.

Traffic congestion is probably one of the worst things you can experience in modern life. A recent study by INRIX showed that people in the United Sates currently waste, on average, 111 hours a year stuck in traffic in the most congested cities. Research has shown sitting in traffic can lead to psychological distress or anxiety and mood disorders up to ten years in the future. But it’s the economic impact that creates the most headlines.

According to INRIX, in 2013, traffic congestion robbed the US economy of $124 billion. Without significant action to alleviate congestion, this cost is expected to increase 50 percent to $186 billion by 2030. The cumulative cost over the 17-year period is projected to be $2.8 trillion – the same amount Americans collectively paid in US taxes last year, or slightly more than the annual economic output of France.

Economic & Environmental Impact of Traffic Congestion in Europe & the US

Evaluating both direct and indirect costs, the study found that in 2013, $78 billion resulted from time and fuel wasted in traffic (direct costs) and $45 billion was the sum of indirect costs businesses passed onto American consumers. At an family level, the cost of traffic congestion is estimated at $1,700 a year. From an environmental standpoint, the expense of excess carbon released into the atmosphere at current prices would be around $350 million per annum in the United States alone.

So with no money left to spend on big projects, what is a completely free way to reduce congestion? Legalize filtering.  And either through dumb luck or brilliant foresight, California has shown that one way to improve traffic congestion is to let motorcycle riders squeeze through gaps in slow moving or stationary traffic. Given that Los Angles has some of the worst public transport for a city of its size on the planet, it’s probably dumb luck.

The legalizing of filtering in Queensland and New South Wales has nothing to do with rider safety. There have been numerous studies over decades that show that filtering doesn’t increase rider risk – in fact in many situations it reduces the risk of injury or even death for riders, especially from rear impacts while a motorcyclist is stationary in traffic. But by legalizing filtering, not only does it encourage existing riders to filter through congestion, the general public may even consider its utility when seeing others do it.

This isn’t pure speculation, either. A detailed study by consultancy firm Transport & Mobility Leuven has found that if 10 per cent of all  cars were replaced by motorcycles in the traffic flow of the test area, total time losses for all vehicles decreased by 40 per cent and total emissions reduced by 6 percent. If up to 25 per cent of cars were replaced by motorcycles, congestion would be eliminated entirely.

Selling lane filtering as being safe will never work. The general public already views motorcycle riding as a dangerous pursuit and seeing a rider squeeze between two cars will potentially lead to the deaths of children and fluffy kittens everywhere. Just look on YouTube or Facebook to see the comments about motorcycles that filter and you’ll get the idea. But to propose it on the basis that letting motorcycle riders filter will actually make it quicker for car drivers to get to work? Hey, why didn’t you say so earlier?

If conservative countries like Australia are beginning to legalize filtering, perhaps at least some places in the United States may start to follow suit.

    In Malaysia, filtering is common in the big cities. Yet, unclear whether is it legal.
