Let's face the fact here Panic, we are aware of Motorways If there a slip road coming off the M there will be a slip road coming on, I am not condemning her daughter in any way maybe it's the way I drive in forward thought, by this I mean & you have seen it Panic, time & time again when the motorist even HGV's have left it until the last min & have no-where to go as there are traffic in the middle when traffic is merging from the left, in-turn slowing down as you know this can be like signing your own death wish with the volume of traffic on the M roads. as you are aware Motorway driving is completely different from your A+B roads as the traffic on them are to a point slower, I may have missed a point here but I still stick by what I have stated, you see it daily I'm sure to much blame is placed on HGVs it's any easy option, a few weeks back I placed a post on regarding window pillar cameras in Car / HGVs in case something like this happens, in this case the the case would have been proven who was at fault.
