Most points have been covered already. It requires less throttle control than the FO8 due to traction control, so at least in that aspect, it's easier to drive.
However, with the extreme corner speeds the BF1 achieves, it's very difficult to maintain the same entry, apex, and exit points lap after lap. Even highly experienced drivers require hours of practice in order to do so. Combine that with the fact that the high speeds result in much greater slipstream effect. As a result getting behind someone even remotely close in a corner almost always results in disaster.
