I can do the maths, but apparently you refuse to. You’re going by what you’ve been taught about speeding on the motorway, how 80 mph is really very close to 70 mph in terms of time. That doesn’t hold true between 20 and 30.
You’re not considering anything, you’re not arguing the points I’ve presented, you’re just trying to fight me. It isn’t working.
If you have evidence that backs up your side of the argument then please present it, like I have with the government’s compliance statistics. Don’t try to pass off the work for making your argument onto me.
