Riding to work yesterday morning (sun,so hardly any traffic) pull on to the island and then this car comes out of nowhere straight across me about 6in from my front wheel!
Had my high vis jacket on so there is no way he couldn't have seen me.
must have done it on purpose

just unbelievable!
Don't rely on high-vis clothing or even decent lights to make drivers take account of you, they are no substitute for a good awareness of what's around you and good cycle craft.
Unless it was being driven by Harry Potter, it's unlikely to have come out of nowhere.
Maybe your view was blocked by bushes, low sun, or he did something quite unexpected like exiting a one way street from the wrong direction. If neither of these then might it have been poor observation on your part?
I know you may think it harsh of me to even mention the possibility, but we cyclists are squishable and anything we can learn from a near-miss can be valuable. I've done it myself in the past and, difficult though it may be to admit it, we have to be honest with ourselves in evaluating incidents like this.
