In my opinion, Donald Trump’s war on Iran has been nothing short of a disaster with no perceptible positive outcomes, no obvious exit strategy, and no real justification for starting it in the first place. Iran now has more power than before, the regime is still in place with more extreme leadership than ever, and the Strait of Hormuz has been closed, causing a huge energy shock. The global market is suffering as a consequence. 

This is not just a spreadsheet issue, and it’s not just something we’ve seen in headlines that hasn’t actually had much of an impact on our day-to-day lives. I saw a petrol station with diesel at over £2 per litre this morning, compared to £1.43 on 1st January. That’s a 39% jump in four months. 

These are the kinds of numbers that we haven’t seen in a long time, but the last time we did, it sparked some of the biggest changes in cycling behaviour and infrastructure that we have ever seen. 

Copenhagen is the perfect example of this, with various historical decisions causing cycling use to surge and stutter over time.

Whether it was banning cars from the centre, trying to increase tram revenue, or simply how Danish people viewed cycling, each saw significant shifts in cycling in what is now regarded as one of the most cycling-friendly cities in the world, where bikes outnumber cars.

However, since around 1975 this boom or bust approach to cycling has disappeared, and instead cycling is seen as the obvious way to get around the city. The idea that any government would rip up cycle lanes would be absurd. 

This was originally a direct result of the 1973 energy crisis, which saw Danish people hit particularly hard by increases in oil prices. The country even banned driving on Sundays to conserve fuel. It literally pushed people onto their bikes, forced governments to build the infrastructure to allow this to happen, and since then, Danish people have simply never gone back. Even when car ownership levels increase, the number of people using their bikes to get around has stayed the same. 

It’s not just utopian Scandinavian countries where these energy shocks have seen an uptick in cycling, either. In the land of gas-guzzling trucks and presidents who deny climate change, the 2008 financial crisis hit particularly hard, and for the first time since the 1970s, more bikes were sold than cars after oil hit over $150 per barrel. After this boom there was a bust, with states not investing in the infrastructure to support more cycling, and sales crashed back to earth the following year. 

We are only at the start of this now. With Trump’s latest idea of blockading the Strait, the slow drip completely dries up, so this may well get a lot worse before it gets better. We are already seeing the knock-on effects, with European airports rationing fuel and the Philippines working a four-day week. 

While there may not be much appetite for it yet, with the current government pushing hard for green energy adoption, this is also the time to push for active travel, as the economic argument is now much clearer than purely the environmental one. Whether they will or not is another question, but we have seen how those countries who invest strategically in cycling infrastructure during these times have had positive impacts.
