From my experience, the wind vector seems to be accurate
Seems means you are not sure and you are not the only one that's what the thread is about. According to FCTM:
A rejected takeoff is a potentially hazardous manoeuvre and the time for decision-making is limited. To minimize the risk of inappropriate decisions to reject a takeoff, many warnings and cautions are inhibited between 80 kt and 1 500 ft.
When even failures are inhibited on take off why should anyone include in the decision making an information he is not even sure of it's authenticity. There is no better situation than take off for keep it simple. If you rejected for ND wind and airbus comes out with it's unsuitability on ground you may find yourself very lonely.
