Between 1995 and 2005, the study estimates that 12,545 deaths and 36,583 injuries in the US could be directly attributed to speed limit increases, while the number of deaths on rural roads jumped by 9.1 per cent when speed limits were raised.
In spite of any benefits to the economy, raising the speed limit would come with a fairly significant upfront cost as well. For a start, the entire motorway network would need repainted and to have its road signs changed, while infrastructure improvements would be necessary to facilitate faster speeds.
The bill could easily run into billions of pounds, and would also mean that major routes would need to be heavily disrupted to accommodate roadworks. Faster cars means that maintenance costs will increase too, particularly given
Britain’s unique climate necessitating road repairs more often anyway.
Driving faster means that drivers will go through fuel quicker as well, with some estimates claiming that upping the limit to 80mph co
