To get to 70mph as quickly as you can. or when it’s needed is nice to have more power to pass quickly and safely. Also what about on the auto-bahn in germany?
The eu also want you to blow everytime to make sure you not impaired from alcohol.. at least that’s not coming to the uk, I don’t drink so would be a joke really.. having to blow everytime you out of the car for 15 mins say..
Also the speedo if it says 70mph you will be going slower than 70mph
The law for car speedometers in the UK
The UK law is based on the EU standard, with some minor changes. A speedo must never show less than the actual speed, and must never show more than 110% of actual speed + 6.25mph.
So if your true speed is 40mph, your speedo could legally be reading up to 50.25mph but never less than 40mph. Or to put it another way, if your speedo is reading 50mph, you won’t be doing more than 50mph but it’s possible you might actually only be travelling at 40mph.
To ensure that they comply with the law and make sure that their speedometers are never showing less than true speed under any foreseeable circumstances, car manufacturers will normally deliberately calibrate their speedos to read ‘high’ by a certain amount.
I set my acc at 78mph on the motorway and have never gotten a speeding fine.. 67 mph in 60 zone, 56 mph in a 50, 45 in a 40 and 34 mph in a 30 and now 23 mph in london in the 20 zone.
