@juliette there is a lot of data on this phenomenon/choice. Caroline Criado Perez discusses it in Invisible Women. Sweden saved a tonne of money by clearing pavements before roads, because that's where slip and fall injuries occur, reducing hospital visits and time off work.

WTI at ~$57 isn’t cyclical noise—it’s structural decay. Since the 2022 spike, oil failed to reclaim trend, printing lower highs as demand erodes. This isn’t one shock but substitution at scale: EVs, efficiency, electrified transport, heat pumps, rail, and China’s oil intensity falling. Now. #EVs
