Those 1900 deaths are more significant than they appear, because they typically affect younger people in the prime of their lives.
For an A&E doctor, a typical 'life saved' would be an elderly person with pneumonia, or perhaps heart failure. If we treat them (as we almost always do) then we're typically buying them a few months of life before the next admission. By and large such patients have life expectancies of months or a few years.
By contrast, A 20 year old man in a road traffic accident may have 60 years cut off his life expectancy.
Secondly, if he survives he may well have a head injury. These can be utterly devastating - nice young lads of previous good character get incarcerated in rehabilitation centres for years on end, filled with antidepressants. They are often disinhibited, sexually and otherwise, start groping the nurses and hurling abuse at one and all; they eventually get let out, at which point their marriages collapse (if married) and they may well be unable to hold down a job...
It's not that bad for everyone of course but it's a depressingly common scenario. Teens and twenty-somethings are more likely to die on the roads than for any other reason.
