Conor McGregor clearly ain't too worried about his dangerous driving case in Ireland ... the UFC star was seen smiling ear-to-ear and talking fighting outside a Dublin courthouse following a hearing on the matter.
McGregor showed up to court early Thursday morning amid accusations that he drove dangerously in his pricey Bentley Continental GT on March 22 -- and he didn't seem all that concerned about the case after appearing before a judge.
The 33-year-old -- wearing a fitted suit, white shirt and tie -- smiled big for photogs who had camped outside the courthouse, and he even discussed a potential return to the octagon with some of the camerapeople.
