When Frank Thomas wrote for Golf Digest, I posed a similar question, framed as with driver technology allowing straighter hits, could we narrow the play corridors. His response was it really hadn't made a difference, so don't go narrowing down those condo canyons quite yet.
There was a 2009 driving dispersion study done at Virginia Tech. D players still need up to 165 foot left and 200 foot right to contain their tee shots from 180-220 yards. Some A, B and C players do, too. It didn't look too different than a driving dispersion chart an ASGCA member did back in the 1970's.
And, the ball was always on the tee. Big heads may allow a bit more distance and perhaps a bit straighter shot on what might have been off center hits (or whiffs) on old drivers, but a well struck ball with a slice spin still slices.
Now, if you are talking only about good players, that might be a different discussion. But, they could always hit the driver, just not as far.
