VIDEO: If we'd hit, who'd have been at fault?

[Innes]

A little incident coming home from Torquay. Question is who'd have been at fault if we hit? Me for coming off the roundabout quicker or him for manoeuvring and signalling at the same time THEN checking his mirror? What do you think? PS date stamp is wrong on video. the internal battery on the DVR is pants and resets itself over night!!
