Things change, attitudes change, only much slower than we think, even looking back.
Drink driving has taken a long while to get where it is, which isn't a perfect place but it is much better than 40 years ago. That's a long time, but there are still some unreconstructed drink drivers, I suspect there always will be.
Trouble is, there's a sense that things are changing for the worse. Going through lights that are not really all that red, speeding, using phones. A marker of that movement is the push back from the rise and rise of the speed camera which is "just to tax the poor law abiding motorist" because of course, breaking the speed limit isn't really breaking the law. The absence of significant road law traffic enforcement is significant, too.
Maybe we're beginning to go back the other way? The emphasis on mobile phone use? The recent West Midlands police action? It will take a while, it might even take wider use of making meatware unnecessary for driving (but REAL men will carry on driving for a while yet)
