What are tips for driving a right-hand drive car in the US?

Key tips: use your passenger-side mirror more aggressively for lane changes since your blind spots are different; position toward the center lane line when overtaking to improve sightline; plan ahead at toll booths and drive-throughs (many RHD owners exit the car or use a passenger); highway driving is the easiest adaptation since lane changes are the main challenge. Most new RHD drivers feel fully comfortable within a few weeks of regular driving.
