“I read ael's posts as the person not drinking at all. After re reading it, I now understand what they meant.”
I’m with you on the misunderstanding, Zacs. I interpreted “a lot of people who didn't drink and drive the previous evening” as people who did not drink the previous evening (so where’s the problem?). But I realise what ael meant was “people who had a drink the previous evening but did not drive (until the following morning)”. Glad we sorted that between us.
“Some smart ass lawyer has probably argued that car park surveillance is an infringement of civil liberties or entrapment.”
I think it’s more the case that there are simply not enough officers to do that, Zacs. Many of them are too busy looking into allegations against people who are dead. It’s certainly not entrapment. That’s encouraging somebody to commit a criminal offence.
I tend to agree that putting resources into preventing mobile phone abuse whilst driving would certainly be a greater contribution to road safety. Lowering the limit by a few points (or pints) will not prevent the hard core of miscreants who regularly drive well over the current limit and they are by far and away the worse problem. All it will do is apprehend those who currently do so within the limit (i.e. those who provide readings of 50 to 79 in blood, 22-34 in breath or 67-107 in urine). Having said that, I’m quite sure most people in that category have no real idea whether they are legal or not and just believe (and/or hope) that they are.
