tachograph:
What you’re saying appears to be different to what you originally said which was " you can if you wish, work 15 hrs total duty time per day every day".
Well you can but only by using reduced daily rest and not by using split daily rests as you suggested 
It looks to me that it’s you who needs things to be kept simple so you can understand them.
No Mate, what I said was to keep things in plain English, but YOU decided that the members on this site were not capable of understanding this, so you decided to give your confusing version.
Whether its Daily Break or Daily Rest, Whether its Duty Time or Whether its Shift Time its still 15 bloody hours from the chart being inserted to being removed, that is obviously the part you cannot accept.
As most intelligent drivers will agree, when they have completed 15 hrs on a chart, they are content with the fact they have “Worked” a 15 hr shift, even if they sat in the cab waiting for a recovery truck to arrive, they clocked up 15 hrs end of story.
By all means answer peoples questions, but when they are asking for a simple explaination that they can understand, you have to use common sense and avoid the complicated gobbledegook, which you obviously prefer to use just to prove a point, I understand your views / opinions but, remember, somebody asked for it to be explained in a way they could understand,

You seem to be implying that when the chart or card is in the tachograph it’s working time or duty time and cannot be a daily rest period or part of a daily rest period, this would mean that anyone who leaves a driver card in over night doesn’t have a daily rest which is of course total rubbish.
Hang on a minute, where the Hell have I implied that you cannot leave a chart in overnight?
All I have stated is that once a chart has been removed after a 15 hr shift !!!
Obviously you are now getting desperate if your having to try and twist things to suit FFS
