Driveclubs biggest issue is that part of it is free on PS+, I expect that to affect sales badly.
Sunset Overdrive, to me looks pretty boring so far, and I don't have a lot of faith in Insomniac to deliver something interesting.
So yes I think both will struggle for different reasons. Destiny on the other hand I think will be big, and as we move into the xmas period there are bigger/better games than the two the OP stated for people to bother with.
