Why do we accept so different risks for different travel situations?
Why are Boeing 737 Max grounded by agencies around the world when a few hundred people are killed but why do “we” allow people to travel by much more dangerous modes without seeing it as something where road safety agencies need to intervene?
In the US, people are switching towards driving SUVs and pickup trucks with higher and higher fronts. These are much more dangerous to pedestrians so why do we not legislate that the hood (bonnet) of the vehicle should be below a certain height?
People are upset when an autostrada bridge collapses but think it is no big deal when people drive into bridge abutments and are killed. But, looking at US data, about five people per year have been killed by structural bridge failures in the last 60 years whereas over 300 people are killed annually in the US when driving off bridges and crashing into rivers or ravines or hitting abutments and other bridge support structures.
In this webinar, Professor Per Erik Gårder (University of Maine, USA) discusses acceptable risk, nominal safety (guidelines by agencies) and perceived safety by travelers.
