On Monday evening I watched Downfall, the new Netflix documentary about the circumstances around the Boeing 737 Max disasters in 2018 and 2019. Inevitably, given the circumstances of those events and my involvement in the debate on smart motorways and roads safety in general, I found myself noting parallels in perception in the Boeing 737 Max and All Lane Running Smart Motorway.
