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.
becasue people are stupid and drive to fast lol
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.
Speed limits in Britain are quoted in miles per hour and in Europe they are quoted in kilometres per hour.
Speed limits change for lots of reasons. Limits have changed to conserve fuel and for accident reduction.
== == There have been so many crashes in the last 100 years so the speed limit has changed to accomodate this and reduce the crashes on British roads
because there have been too many accidents. changing the speed limits means there is a decreases in accidents
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.
coz there has
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.
The speed in Britain is 70 mph on motorways. In Canada it is 100km on most freeways, and in Italy it is either 130 or 150 depending on which Autostrada.
There have been changes to the speed limits in Britain for several reasons. The amount of cars on the road (which has increased dramatically), the age limit for driving which has changed because cars are cheaper and younger people can afford them and the types of cars that are on the road e.g 4X4, Vans, lorries, Super cars and standard cars. Cars have been developed more and more over the last hundred years which means they can go faster and faster due to better fuel consumption and fuel usage
