On at least two occasions I have posted on reasons other than random testing being behind the drop in drink driving and resulting deaths and injuries.
However, there is empirical evidence linking random testing and immediate and demonstrable step changes in related deaths and injuries.
You choose not to see that or the full picture. There are a wide ranges of factors at play.
As said before, societal changes where drink driving is strongly disapproved of, people drinking less, better infrastructure, public transport, safer vehicles all contribute to reducing road deaths.
Nobody has argued otherwise. But what is also evident in other countries that have taken the step, random checks make a big difference. Right from the start.
And those countries have not gone down this fictional slippery slope.
