LOL! Wow, you really got into this one. The numbers quoted were not fatalities, they were number of collisions. Your idea of safety is not dying if involved in an accident, where mine is not getting into an accident to begin with. Differing views, that's all, and not worthy of mind-nuimbing internet research in my opinion. If you disagree with the number of accidents I quoted then feel free to argue them with the National Highway Traffic Safety Administration. I believe they have an 800 number and would love to hear from a concerned taxpayer. ;)
Also, to quote the numbers above is misleading since several types of roadways are lumped into general categories. Federally aided road systems are not merely high-speed, multi-lane highways. They also include urban and rural routes, from main roads to farm roads. So, your numbers could actually be used show that fewer people die on Interstate highways than on smaller roads, rural and urban. That too would be inaccurate however, assuming that's even what we're looking for. To be really accurate we also need to establish whether we're talking about fatalities, injuries, collisions, etc, or what mixture of such. I really don't think anyone is interested in being quite that pedantic, myself included.
Boy did this ever get off-topic somehow! LOL! Apologies to James. ;)
