I recall an incident in the UK where a lorry driver had stopped round a blind bend to make a delivery, a car piled into him and killed the occupants of the car, the lorry driver was charged and prosecuted successfully with manslaughter, it seems that the car driver in your case was negligent in showing due diligence to the safety of others in parking in the way in which he did, it was live carriageway and due diligence has to be shown, it would appear that the car driver failed to do this, thus is culpable to a certain degree if not 100%.
Ignore these fucking jobsworths on here who say that you should drive like a spastic on acid and be prepared for all and sundry, if that was the case, none of us would get anywhere.......We all have a responsibility for the safety of each other, however, when some one acts foolishly, then the responsibility stops with them and they should accept the consequences. Do not listen to the fuckwits on here, because that is what they mostly are.......FUCKWITS.
How about supplying a link to that story? Manslaughter? Sounds utterly implausible...
Of course, the car driver can always be prosecuted for dangerous parking/whatever - but the reason he was stopped (whether to take a picture or as a result of a breakdown, for example) makes no difference.
The simple fact is that someone failed to negotiate their way past a stationary object safely...
