The Growing Safety Crisis of 'Carspreading': How Larger Vehicles Threaten Urban Life and Road Safety

AI Summary
A new study reveals that cars have been steadily increasing in size since 2000, a phenomenon dubbed 'carspreading' that could lead to an additional 2,600 crash deaths annually by 2040. This trend not only threatens public safety but also reduces urban parking spaces and increases emissions, creating a multi-faceted crisis for cities worldwide.

The Lead

Cars have grown 1.2cm longer, 0.5cm taller and 0.5cm wider each year on average since 2000, in what green groups call "relentless carspreading." This increasing vehicle size is projected to lead to an extra 2,600 crash deaths annually by 2040, according to a new analysis by Transport & Environment (T&E).

The Technical Breakthrough in Vehicle Sizing

The analysis of new vehicles sold in Europe found that car bloat has progressed at a roughly steady rate for two and half decades even as family sizes have fallen. This trend is frustrating drivers, with cities set to lose 8.5-14% of on-street parking by 2040 if the historical trend continues unchecked. London and Berlin are each set to lose about 100,000 parking spaces.

The Safety and Environmental Impact Data

Compared with a scenario where car sizes were "right-sized" to 2015 levels, current trends would lead to an extra 2,600 vulnerable road users dying in crashes each year by 2040, 79 of them children. The extra resources needed to move the larger cars would equate to an extra 100m barrels of oil imports and 22.5 terawatt hours of electricity.

The Urban Planning Crisis

The relentless growth of vehicles is creating significant challenges for urban planners. As parking spaces disappear, cities face difficult decisions about how to allocate increasingly scarce street space. The problem is compounded by the fact that larger vehicles often take up more than one marked parking space, further reducing available parking.

The Future Outlook for Vehicle Regulation

Experts recommend capping bonnet heights and car widths, changing taxes to discourage people from buying bigger vehicles, and tightening vehicle standards so they considered the visibility of young children from the driver's seat. Without intervention, the energy demand from larger vehicles could be equivalent to the output of an extra 1,500 offshore wind turbines, placing additional stress on already strained energy grids.
