Other people made research already, our govt keeps lowering the speed limits.. but cannot blame our 'educated' menteris for not reading traffic studies of other countries which offers their study results for FREE.
Some excerpt
What's the history of speed limit laws in the United States?
Speed limit laws, which date to 1901, traditionally have been the responsibility of the states. Before 1973, when Congress responded to oil shortages by directing the US Department of Transportation to withhold highway funds from states that did not adopt a maximum speed limit of 55 mph, speed limits on rural interstates in most states ranged between 65 and 75 mph, with the majority of states setting rural interstate speed limits of 70 mph.7 In urban areas, most states maintained 55 mph speed limits before the national maximum speed limit was established.
By March 1974, all states adopted the 55 mph national maximum speed limit. As concerns about fuel availability and costs faded, however, and speeds began to gradually climb on US highways, Congress in 1987 allowed states to increase speed limits on rural interstates to 65 mph.
The National Highway System Designation Act of 1995 repealed the maximum speed limit, allowing states to set their own limits for the first time since 1974. Many states quickly moved to raise speed limits on both rural and urban interstates and limited access roads. As of September 2008, 33 states had raised speed limits to 70 mph or higher on some portion of their roadway systems.

With the ops sikaps statistiks showing that accidents in cities being the highest (where cars are the slowest), followed by federal roads and highways (where cars travel faster) You'd think they'd understand that 'too-slow driving' people tend to change lane suddenly, chat on the phone, cintan inside car, tengok awek, turn suddenly and etc are the major contributors to accidents, at least in the malaysian context.
Even in the study.. whether they increased the speed limit or not, it doesn't affect accident & crashes statistics at all...
You can't cure idiotic(brain slow, car also too slow) drivers by imposing laws to make the rest of the population as stupid/slow as them...
Drivers make up the math.. want to reduce accidents? Sell less cars, or accept the fact that not everyone has the mental or physical faculties to DRIVE.
But of course, with P1 and P2 hungering for sales of their cars... FAT CHANCE anything will change.
But then again.. when you consider the tires most people are using in Malaysia.. I'm not really thinking of advocating higher speeds, just that I'm frustrated of meeting people on the highway, or some federal roads going really slow (some at 35kmh!) and not really travelling in a straight line, making overtaking a daunting and nerve wracking affair.
