Why is there a problem with the 80mph speed limit?
Why is there a problem with the 80mph speed limit?
“Any move to raise speed limits on motorways to 80mph is fundamentally an issue of safety. Part of the problem is that at present, there is a high proportion of drivers that break the 70mph limit, and drive nearer to 80mph. If the speed limit were to be changed to 80mph, there is a risk that the new default becomes even higher.

Is it worth it to drive at 80 mph?
If you drive the entire 400 mile distance from London to Edinburgh, you would only save 40 minutes, and that assumes that you maintain a constant speed of 80 mph the entire time, neither accelerating or decelerating.
How long does it take to stop at 80mph?
Stopping distance at 80mph will be 400ft (an increase of 85ft from 70mph) (see article on stopping distances and kinetic energy at https://www.riodrivingschool.co.uk/stopping-distances-and-kinetic-energy/) you only save yourself 6 seconds per mile!

Which is more dangerous 70 mph or 80 mph?
Kinetic energy depends on the square of the speed; if you double the speed of an object you quadruple its kinetic energy. An increase in speed from 70 mph to 80 mph is a 14% increase in speed but this results in a 31% increase in kinetic energy, making the car – in a sense – 31% more dangerous to other road users.
