New cars are being made with higher quality and their engines are capable of higher speeds. Roads are safer than the earlier roads. During times of fuel shortages and rationing, speed limits were lowered to reduce fuel consumption. Speed limits have been adjusted to account for the human reaction time and modern engineering to help keep people safe.
Speed limits change for lots of reasons. Limits have changed to conserve fuel and for accident reduction.
Perhaps, the changing(increasing) number of population which most likely results to increase in the demand for transportation and therefore to the change it speed limits to regulate traffic and safety of commuters and drivers.
Because people are going too fast on the road.
Speed limits for cars in Great Britain have changed over the last hundred years due to improvements in road infrastructure and technology, advances in vehicle safety features, and government initiatives to reduce traffic accidents and fatalities. Additionally, changes in societal attitudes towards road safety and environmental concerns have also influenced speed limit adjustments.
The national speed limit was changed to 65 miles per hour in 1974 as part of the Emergency Highway Energy Conservation Act, which aimed to reduce fuel consumption during the oil crisis. This speed limit was in effect until it was repealed in 1995, allowing states to set their own limits. Some states had already raised their limits before the repeal, leading to a variety of speed limits across the country.
for the lulz British roads are typically very narrow while there are a few "highways" as we know them they still are small compared to our interstates. Because of the narrow, winding roads and the high cost of petro "gasoline" speed limits have remained on the slow side.
becasue people are stupid and drive to fast lol
As a fuel saving measure during the oil embargo crisis.
Parts of the German Autobahn do not have posted speed limits.
The jobs changed from being a slow paced, low production working environment to a fast paced high production environment. The factories and other jobs completely changed in ways like Health and Safety, production speed, and the age restriction and limits.
Yes Germany does have speed limits but on a lot of motorways they dont :)
They are not allowed to exceed speed limits
