dude...if more people are dying this already disproves your claim
there has been no decrease in accidents. i remember reading about speed limits & they had the statistics for auto accidents...little to no change over the years
It doesn't seem to me that you read those reports. Instead, it sounds like the TV news blurb version.
The lower limits showed little decrease in crashes because no one actually slowed down to comply with the lower limit.
The primary conclusion of this research is that the majority of motorist on the nonlimited access rural and urban highways examined in this study did not decrease or increase their speed as a result of either lowering or raising the posted speed limit by 4, 10, or 15 mi/h (8, 16, or 24 km/h). In other words, this nationwide study confirms the results of numerous other observational studies which found that the majority or motorist do not alter their speed to conform to speed limits they perceive as unreasonable for prevailing conditions.
Accidents and deaths definitely increased with the increase in size of vehicles.
Sport utility vehicles have the highest rate of deaths occurring in rollovers. Cars such as the Ford Explorer, Toyota 4 Runner, Isuzu Rodeo, and Honda Passport have been involved in SUV rollovers that have ended up in serious injuries and death. SUV rollovers are almost three times more likely to occur than the average passenger car, and government tests indicate the most stable SUV is still more unstable than the most unstable car. What does this say about the safety of SUVs on the road?
But, there's no dispute regarding increases in fuel efficiency:
Lowering speed limits can potentially reduce total fuel consumption. According to literature we reviewed examining the impact of the national speed limit enacted in 1974, the estimated fuel savings resulting from the 55 mph national speed limit ranged from 0.2 to 3 percent of annual gasoline consumption. According to DOE's 2008 estimate, a national speed limit of 55 mph could yield possible savings of 175,000 to 275,000 barrels of oil per day. This range is consistent with estimates of the impact of the past national speed limit. According to the Energy Information Administration, total U.S. consumption of petroleum for 2007 was about 21 million barrels of oil per day.
That's 100,000,000 barrels a year saved by lowering the limit to 55, using the existing fleet of lousy efficiency vehicles Americans (and no one else in the world) drive, that's only a 3% increase in efficiency.
An average fleet mileage increase from the current 20 mpg to 40 (the current average in Europe) mpg would knock a Billion barrels a year off the current 3.7 billion barrels a year we import. Japan's average fleet efficiency is 47 mpg.
IMO, anyone who buys that Ford and GM couldn't increase the fleet efficiency to the highest in the world and reduce oil imports (and, therefore, our staggering current account deficit) is delusional.
How many lives would have been saved if we hadn't illegally invaded the ME to create an oil monopoly to satisfy our lust to burn the shit?
The bottom line in any case is that it's all moot. When the carbon footprint tax is implemented, Americans will run, run, run to smaller, more fuel efficient cars... period. We'll be taxed into the same place Europeans, Japanese and Asians have been for years. It will simply be too expensive to drive a guzzler.
