Just for you levey

On the questin about stats before and after the introduction of safety features on vechicles. There are two broad catagories of safety featues.
Features that aid in the reduction of incidents. eg taillights/brakelights ie likleyhood
Features that aid in the reduction of the severity of an incident eg airbags. ie consequence
Traditionally, features that reduce the liklyhood of accidents cause a sharp immeaditae drop in incidents that direcly relate, but there is a gradual climb back to the previous levels in 12-24 months. This is beleived to be directly related to users becoming complacient with features, and this is measured on a per capita basis, not static numbers.
Features that reduce the consequence and their related reduction in incident liklyhood are harder to measure since the data that is collected from incidents is almost exclusivly lilyhood related. eg were your taillights workig? Not just that, but features that reduce the consequence on an incident fall into the realm of attitude rather that physical items, so the only way to gather data is by interviewing people with carefully crafted questions to gain the right information.
Also, if you look at the safety features that have been introduced into cars over the last, say 30 years, features that reduce the liklyhood are not as common as consequence reduction features, yet it is liklyhood type features that wil save lives as they prevent incidents rather than just lessen the consequences.
Now hopefully that all made sense...

or did you want me to make it a little eaiser for you levey... all the floorboard dust must be frying your brain, or maybe its just all that time with Joel...
