From our court reportage, it seems to be prevalent among the older drivers, particularly if they're recidivist offenders.
The drinking age becomes a irrelevancy when time and again cops are pulling up people who are in their 40s or 50s, with one wine too many in them, or worse. The zero alcohol limit, for under-20s, I do applaud.
Lowering the speed limit is a nonsensical idea. Again, whether it is 80km/h or 100km/h, it is not going to make a difference to a person who likes to go fast. It's just the fine is a somewhat bigger if you get caught.
There is a comfort zone for driving on straight, rural roads like ours, and that is around 100km/h.
The English have it slightly better than us with a 60 miles per hour limit, a bit faster. We can comfortably drive at that speed, on open roads. Drivers self-regulate when they encounter wind, weather conditions and tight curves.
That's experience and education and good sense, and no amount of tinkering with the speed limit will top those skills.
There might be some bad luck in your life, when it comes to cars and alcohol. But bad choices, not regulation, will likely mean your life will be short.
