I don't drink, so this does not effect me personally, but in my experience those who do regularly, are perfectly safe after a beer or two. Two is, I gather enough to put some over the limit, so 05 is probably going too far.

Why is there always some clown trying to make a name for them selves by attacking the lives of others. Perhaps this gentleman is feeling ignored, so has to burst into print, to gain the attention he desires.

It's always the stick - why not a carrot?

How about, if you have 0 alcohol, you may drive 10km/h faster?
If you are an experienced driver of over 5 years without incident, drive an ordinary car (as opposed to a truck or a bus, etc.) and commit in advance to not drive your car with any alcohol, then you should get 20 km/h more in dry weather conditions.

Speeding is dangerous, but driving faster than the formal speed signs is not speeding because the signs are irrational.

I don't drink alcohol myself, but I think that if zero-alcohol is introduced, the road toll will actually increase. Why? Because grandma will tell grandpa: "I know that you are very tired and you cannot see well at night, but this time darling you will have to drive us home because I had a little glass".

A little more indication that lowering the permitted alcohol level works,

On speed limits,
as the Gwydir Highway (50 zone) leaves Glen Innes there is a section almost devoid of buildings, nothing on the left of the road but a factory set well back on the right, then a house and the 100 sign then two more houses, whose occupants are presumably not as important as their neighbours in the first house.
Other streets that are devoid of houses in parts are in 50 zones.

By contrast, Inverell has one residential street with a limit of 70 and a limit of 60 on the road boarded by the hospital and the high school, with, incidentally, a car concealing dip with the broken centre line leading the unwary into a trap.

The residential street with the 70 limit allows traffic, including semi-trailers travelling to the north-west of the town to bypass the town centre so is quite popular and for at least the last five years has had no centre lines at all, even though there are three blind curves.
So much for road safety.

Any alcohol has an immediate effect on your senses; people who say that they can 'hold' their drink really cannot. But you can't tell drinkers anything. Only totally sober people can tell how drinkers qickly change when they've had 'only' one or two. Australia, as a country, has a serious problem with the stuff.

The road safety junkies tell us that speed kills, but it doesn't in the real world.

A couple of years ago I was talking to a Sargent of police in Canungra. Gold coast side of the army base there is a small range, with a typically twisty bit of road over it.

The speed limit through there had been 100Km/H for years. Occasionally someone, often Gold Coast Tourists would run off this road into the bush. The Police Sargent opined it was usually people driving slowly, rubber necking at the views, as most crashes were slow speed.

The road planners in their wisdom reduced the speed limit to 80K on this stretch "to improve safety" of course. The Sargent found the number of off road events increased considerably.

To combat this rash of crashes our idiot planners reduced the speed again to 70 this time. Yep you guessed it, that Sargent found again the off road events increased again, mostly of visiting tourists. He surmised that at the slower limit the tourists felt safer to look around, rather than at the road, causing the off road events.

They made a submission to bring the limit back up, but the planners think they know best, & the slow limit remains even after the road was widened, & overtaking lanes built on either slope.

Yep the road safety group like enforcing their will, even when their systems are proven wrong.

I believe I am acutely qualified to answer this one.
My credentials are;
I've been driving, off road, farm, etc, since I was four, had to have a few mods done to the controls.
I am now 69.
I still hold every driving license available to me and have done so from the day I was eligible to apply for them.
I still hold a heavy, multiple trailer endorsement. (road trains)
I still hold a "for hire or reward" license. (I can drive taxi's or coaches, any size)
I had my own planes, so I had a pilots license. (let it go because I could not be bothered to do the minimum hours per year as laid down by the d!ckheads who can't fly)
I got my license when I turned 17 as was the law of the day.
I have had my license for 52 years, and here's the best bit; without incidents, crashes, smashes or clashes.
I've never been pinged for speeding or other traffic violation.
I got pinged once for not wearing my seat-belt according to the law, even though I explained I had not long been out of a three month hospital stint for open heart surgery.
He may as well have said go and get f&(ked for what good my explanation did.
I was wearing it, but under arm so as to not put pressure on my chest because it was still in repair where they had cut me open through or around the sternum.
Anyway, this country was settled with liquor and 200 years on, nothings changed.
I believe that Aussies are stubborn, arrogant and immature, and as some have explained, no end of license removal or suspension is going to stop these morons.
So the answer is, let them drink and let the dice fall where they may.
The law is a dishonest scum-bag disgraceful lot, with money as their agenda.
They do NOT care about people, because if they did we would see a total ban on alcohol, but it's too lucrative to even think about removing the current fines system.
