I have seen similar matters impact the closing on a sale of property. In one case, the attorney would only close AFTER the seller provided a remedy and agreed to pay out of pocket to relocate the neighbor's encroaching drive (to the tune of about $4,000 because the seller had to make a last minute decision and he wanted the house to sell).
In a second case, the attorney postponed the closing until the drive could be cut, which was all that he required, so the seller rented a concrete saw, cut a diagonal/corner section the same day, and closing occurred a day later. The attorney didn't care that the concrete remained, as long as it was physically separated, but I personally would not want someone still using it to drive over/onto my property to access theirs.
As others have stated, dealing with it now gives you better options than waiting and the situation changes for the worse. Knowing about it and not dealing with it now could impact a decision down the road by almost admitting that the neighbor had your okay to use it because you took no action.
