    "description": "Buses inherit some of the same intuitions that make people fear planes and trains: you’re enclosed, you’re not driving, and the few crashes that do happen tend to be dramatic multi-casualty events that make the news. The gut reading of bus safety is that it is \"somewhere between a car and a train, probably closer to a car\". The per-passenger-kilometre data says the opposite: bus and coach travel sits alongside rail and commercial aviation in the safest tier of all motorised transport.\n",

The per-passenger- kilometre figure used here (~0.3 deaths per billion pkm) is a developed-country, scheduled-service number from the EU. It does not describe an informal minibus on an unpaved LMIC road, which can be an order of magnitude or more worse, and it does not describe a modern European intercity coach on a motorway, which is measurably better still. Within the \"bus\" label sit school buses, urban transit, intercity coach, and chartered tourist coach — all with different fleets, different driver regimes, and different per-km rates. The normalized lifetime number is also highly exposure- dependent: for a reader who takes a bus twice a year, the real lifetime probability is effectively in the noise; for a daily commuter in a country with weak vehicle inspection regimes, it is meaningfully above the headline.\n",
