I have a friend who managed to roll his car about 3 times in an accident. He'd have got away quite lightly if it hadn't been for his hard briefcase sitting behind the front seat. People have made fun of me when I refer to a carrier bag as my "executive briefcase", but it's never going to cause me serious head injury!
Well now we've sorted out the drink/driving laws and projectile injuries, did the OP make the journey, get made redundant, set off into the sunset and indeed is he still here?
It is easy done Steve and I fear that we have lost the OP and will never know the answers to my questions. Threads can take on a life of their own which bears little resemblance to the post that started it all.
Here in the UK there is no law to stop you sleeping in a motor vehicle, so I do not know where that came from. Lay-bys are there for having a rest/sleep, that is why you see the lorries parked up overnight. No stopping on motorways for a kip, though; and don't use the parks at service areas, for if you sleep longer then the permitted staying time, then they try to fine you with a supposed 'parking fine ticket.'
It didn't make sense to me either. If you are tired enough, surely any law enforcement program would want you to make sure you rest before driving further. It's an easy way to prevent accidents, so why shouldn't it be allowed?
Stayed in the back of my RVR-Space Runner once. Lesson lerned was that in future more blankets are needed and although the reclining rear seats are okay it would be better if the rear bench was removed all together to get more space.
Pick your location carefully and you probably won't get any hassle. I've found motorhomes in a few of my favoured shooting venues before now, judging by the time and the lack of signs of life I rather doubt that they'd arrived that morning.
As for flying objects, that's part of the reason why my car has a rear strut brace. This is essentially an aluminium bar bolted across the tops of the rear spring mounts behind the back seats. It should do a pretty good job of stopping large or heavy cargo from demolishing the seats in a crash.
Talk about a thread taking on a life of its own. The OP got a flurry of replies in 2008 and then disappeared. It was revived in 2011 with no sight of the OP and prompted me to ask several questions about what he decided to do, was he made redundant etc and it has now been revived again??
