Yup, all these things vary the relationship but can be easily re-calibrated by a glance at the speedo,
Yes, but only for that moment: "low limits & 30creep"

... you seem to be saying that the majority of drivers are entirely reliant on their speedos 100% of the time to judge speed. whilst i can beleive that to be the case for absolute speed with any accuracy i find it hard to beleive i'm so supernaturally gifted that i can use these triggers to pick up a change in speed between speedo checks.
You cannot dispute the possibility that your ability to judge speed from indirect observations is better than average; I suspect it is. It must be better than mine (I sometimes inadvertently creep over).

I agree low limits & 30creep is an issue, but spotting the change and repeaters really shouldn't be an issue for most drivers.
What about after the terminal signs?
Repeaters not necessarily needed in a 30

Not sure about people not setting out to exceed limits, any stats to back this up ofr just hearsay?
It's common sense (well, so I think anyway). Who sets out to break a law, especially one that effectively removes 1/4 of one's entitlement to drive for three years? I know I don't.
Would you like to set up a poll on this forum to get a good indication? Some might say the population of this forum should yield a positive skew

So on the one hand 'we' are campaigning for smarter enforcement alongside driver education & improved standards of driving, disliking the various active driver assistance systems being introduced on cars due to drive dumbing down, yet seem now happy to accept VAS as a good thing even though it appears to be a crutch for poor driving standards.
I don't think so. VAS is good for those who suffer a lapse in concentration in one specific area of driving, or those who are more concerned with potential hazards ahead instead of the position of a needle on a dial. Remember, this applies itself very well to "low limits & 30creep".

Sorry chap you've lost me there.
People have exceeded the limit, as indicated by the speedo, during their test and still passed (I'm sure there is a member who claimed to have done that).
Sure one can fail the test for exceeding the speed limit, but can one fail for doing a genuine and legal 23 when the speedo is reading 31-32? (legislation allows this amount of error)
