LEFTLANE
Country-neutral guides for licensed drivers crossing into left-hand traffic. Why the brain resists, what changes physically when you swap sides, and how to rehearse the moments where habit fails.
Why licensed drivers drift to the right after a turn — and what motor-learning research says about rebuilding the instinct. For anyone nervous about driving on the left for the first time.
The geometry of clockwise circulation, the physics of crossing oncoming traffic on a right turn, and the discipline of keeping left after a turn instead of drifting back to old patterns.
LeftLane is a free browser simulator that puts you in the moments these guides describe — the right turn, the clockwise roundabout, the post-turn drift.
