His match-winning goal wasn't just enough to earn Hearts a first SPL victory of the season. The strike would have lit up the Gorgie ground even if the contest had been played in brilliant sunshine.
Driver has been troubled by heel and hamstring problems this season and how much these ailments have hampered the efforts of Csaba Laszlo's side was blinding illustrated when the English Under-21 internationalist smeared an 18-yard drive into the top corner of the net after half an hour. All other efforts from both sides, Kilmarnock having too many for Hearts liking, lacked the finesse of Driver's drive, but at least the fixture is now out of the way.
It has seemed bedevilled since it became a late postponement on Saturday after the Kilmarnock team bus struggled to negotiate the M8 following an accident. Following that, concerns were then expressed over the midweek re-arrangement because only three Tynecastle floodlights were operational following a fire.
The encounter at least came at a good time for the two keepers deployed. Injury to Alan Combe allowed recent loan signing Mark Brown to make his debut for Kilmarnock. At the other end of the pitch Marian Kello was the beneficiary of an illness that deprived the home side of Janos Balogh. Brown was the one of the pair who had to pace and prowl his area in preparation of activity. That came in just about the first meaningful forward push from either side when Brown confidently grasped a Gary Glen cross from the left.
Hearts, predictably, did most of the probing in the early stages. But this didn't amount to much more than the backline of Jim Jefferies' side being kept on alert by the movement and trickery of Suso Santana, David Obua and Driver. And it was Kilmarnock who threatened first.
A burrowing run from Craig Bryson on 21 minutes supplied Conor Sammon with the confrontation's first real shooting opportunity. The Irishman got enough on his hit from 14 yards out to give Kello kittens, but the Slovakian avoided mishap by beating the ball away as if pawing at a buzzing fly. In that instant, it was impossible not to wonder if the outcome would have been different were Kevin Kyle the striker putting his foot through the ball. The Ayrshire club's renaissance man was listed among the substitutes despite suggestions he could be missing for a month after sustaining the knee injury that robbed him of a return to the Scotland set-up.
But even with Kilmarnock's only three points of a three-game season being those secured by Kyle's opening day hat-trick, the night-trippers were still better placed than their winless hosts. Until, that is, Driver struck, the excellence of the execution enhanced by nifty footwork that allowed him to nick the ball away from Jamie Hamill before letting fly.
Kilmarnock's response was to produce an emphatic one. They should have ended the first period on level terms and only David Fernandez will know why they didn't. It seemed harder for the forward to do anything else but nod the ball past Kello after a Sammon flick-on from a Tim Clancy throw-in had provided him with a glorious opening seconds before the interval. But he eschewed the easy by heading over.
Jefferies' men didn't let that miss go to their minds and hardly let Hearts out of their own half for the quarter of an hour that followed the restart. In that spell - by the end of which Kyle had replaced Fernandez - Bryson deserved better than to see a clever backheel bump the post. Gradually, though, Laszlo's men began to find space in their opponents' final third.
Suso should have made more of the acres of it that had him stooping to pick his spot with a header yet only succeeding to put it close enough to Brown to block. Michael Stewart then hoofed over wildly before Hearts fans survived a couple of nail-biting dying minutes after seeing the team lose late late goals and three league points in their last two SPL matches against Rangers and St Johnstone.
