Your cycling fallacy is…
“Bisognerebbe usare un abbigliamento ad alta visibilità in bici”
The response
Il buon senso suggerisce che l'uso di indumenti riflettenti renda le persone in bici più visibili, e dunque più sicure.
Però questa non è una conclusione sostenuta da fatti. Diversi studi suggeriscono che gli abiti ad alta visibilità hanno un effetto trascurabile sulla sicurezza delle persone che vanno in bici, e parimenti sul comportamento di chi guida. Peggio, in certe circostanze il riflesso degli indumenti fluo può ridurre la visibilità: vi sono stati casi in cui tali indumenti sono stati citati come fattore aggravante in incidenti mortali.
Invece di insistere affinché le persone portino indumenti speciali quando vanno a piedi o in bici, dovremmo concepire alla base delle strade sempre sicure per tutti coloro che le usino.
