Either a lifetime ban is no less reasonable in principle than any other ban, or we might as well stop banning people and do something else instead.....
Just to spell out my own position clearly:
I think that the threat of a ban is effective against people I've already described as
bourgeois. That's been the success story of the breathalyser. Beyond that, I think that the success of disqualification is in the eye of the beholder, ie those
bourgeois who would comply with a ban and assume that compliance is general are glad something is being done and at little cost. I'm also pretty confident that in most cases, it's pretty much bad luck that leads to a conviction for driving while disqualified. As fewer police resources are directed towards "roads policing," so the odds against being caught lengthen.
On the issue of lifetime bans, I'll throw in that they were ruled a breach of civil liberties almost fifty years ago. Prior to that, we used to have repeat offenders with bans similar to American prison sentences, measured in hundreds of years. On a personal note, I discussed this at the time with a family member of one of the people appealing to whichever European Court. They told me that the person in question was only appealing because while the appeal was in progress, it extended their remand privileges. The person in question had never bothered about bans in the past and wasn't going to bother about them in the future, no matter what the decision from Europe.
Not strictly relevant to this thread, but at least in respect of totting up, the deterrent effect of the threat of disqualification is undermined by the "hardship" loophole and the growing feeling that it's easy to avoid a ban.
