For roads we have the phrase "build it and they will come". Any increase in road capacity will over a (relatively short) period in time be matched by an increase in cars, and thus the street or area just as congested as before.
Now it seems like a similar statement might hold for automobile safety devices. As the below article implies, technically improving the cars does not help. Drivers will feel safer and simply drive less safely until the same accident rate is obtained.

Dr. Evans, who is the president of the International Traffic Medicine Association, contends that so-called safety devices in cars, particularly air bags, have had an insidious and deadly effect on driver behavior.
He said that as recently as the late 1970s the United States had the safest highways, using the measure of traffic deaths per 100,000 registered vehicles. Today, he said, the United States is in 12th place and sinking.
“If the United States had simply matched Canada’s performance over that period,†Dr. Evans said, “annual U.S. fatalities this year would be 28,000, rather than more than 41,000.â€Â
He said that since the mid-60’s, American have spent billions of dollar seeking the perfect technological fix to prevent fatalities. Their solutions, the air bag and other “passive†devices, have only compounded the problem. Other industrial nations, Dr. Evans said, have pursued a more balance approach -- better and early driver education, stricter enforcement of traffic and seat-belt laws, use of cameras to detect speeding and red-light running and campaigns against aggressive driving.
“We have just receive the wonderful good news that the air bag is killing fewer people than it used to,†he said. “When was that an advertisement for a safety device, that it’s killing fewer people than it used to?â€Â
Dr. Evans said that the air bag and other safety devices had the same effect collectively as advances in cardiac medicine. Angioplasty and bypass surgery have not decreased the rate of death from heat disease, he said and might have convinced people that there is a technological “cure†for the unhealthy behaviors that lead to heart attacks.
“We see American collectively driving a couple of miles an hour faster because of a false sense of security,†he said. “And that collective increase in speed more than washes away the alleged benefit of air bags.â€Â
