easy pull for the cops, thats why they did it, hot their quota etc
rubbish.
The law is pretty clear on the being in charge of a motor vehicle thing, and if being sat in the driving seat with the keys in the ignition isn't being in charge of one I don't know what is.
Given that the guy pleaded guilty when he presumably had the best legal advice money could buy if he wanted it makes me think he (and his lawyers) knew he didn't have a chance.
It's also something I'm actually quite glad the police do take seriously, otherwise all it would take would be a drunk driver to pull over out of sight of the police and say "honest guv I was just sleeping".
As for why the police even noticed him, I'd guess they either had a call from someone, or noticed someone in a car who either looked drunk or unconscious, in either case they'd want to check it out (if for no other reason than to protect themselves if anything happened).
It's incredibly foolish to get into the drivers side of a car whilst drunk, it's pretty daft to get into the car at all with the keys when drunk given how much publicity there is about drink driving, and the fact the law is pretty clear.
If he'd been in the passenger side, with the keys in the boot it might have been arguable for him, but keys in the ignition and turned, him in the drivers seat not a chance in hell of getting off at least the "in charge of" offence if not "driving", or "failing to provide".
Hence the "failing to provide", as he failed to provide a sample when asked (And iirc Asthma is not a defence, unless you've got a very serious case and the medical proof).
