But there is a fundamental difference between fatal car accidents and gun homicides: in most accidents, there person who caused it did not intend to kill someone. It might have been a momentary lapse of concentration. Or bad conditions. Or deliberately dangerous driving with a disregard for other people's safety. With guns, the person who pulled the trigger usually intended to injury or kill someone.
And the other difference is that society is does not consider road traffic deaths to be acceptable - an unavoidable consequence of using cars, a price worth paying for the freedom to have private car ownership, or the economic benefits. Instead, efforts are made to reduce accidents. Or at least, that is the case in the UK and western European countries. I presume that the USA is similar? In the past 50 years in the UK, road fatalities have reduced from about 8,000 a year to typically 1,800, despite a large increase in population, car ownership, car usage, and traffic congestion. This has been achieved through many different areas, such as: improved car safety, better emergency treatment for victims, changes in road layout and design, making drink driving socially unacceptable. We didn't say "cars must be banned" nor "it's drivers who kill, not cars" as an excuse to do nothing. Although having just looked up the USA statistics, the reduction has been much smaller, I'm now wondering if these comments apply in America?
