I am not a driving instructor per say but I have taught a few driviers.
If the vehicle is a standard transmission, clutch /brake corellation, coupled with gas on/gas off, takes getting accustomed to while keeping the vehicle to follow the lane.
If automatic transmission. brake/gas on/gas off, while keeping the vehicle in its own lane.
With regard to keeping the vehicle in its own lane, I teach pupils to corellate a piont on the vehicle (Fender or a point on the wiper blade) a certain distance from the curb or line marking of the lane.
