It’s not “drifting”, at least for me it’s not.
Yes, I can maintain spacing in the center of the lane, without drifting.
Thst doesn’t mean I always maintain position in the center of a lane, however.
In a road with one lane, and on coming traffic, generally stay “high”, that is closer to the on coming lane. Especially for narrow roads. This keeps your tires out of the gutter where debris accumulation can lead to picking up a flat- of an on comical car comes along I’ll fade “low” to give them as much space as possible.
On residential roads that have no markings at all, I’m in the center of the road- to give myself space to come away from any given hazard.
Similarly, if there’s a cyclist or pedestrian, I’ll fade as high as I can go to give them more space.
On highways and multi lane roads I’m centered in the lane- again to give myself spacing.
If you find yourself drifting, that is, moving away from where you intend your car to be, that’s a problem you should figure out. It’s not particularly safe (what happens if you drift into the shoulder? Another car?) and bluntly, cops might decide your driving drunk.
