Disagreements during driving lessons can happen, but it's important to handle them calmly. If tensions rise, find a safe place to stop the car and take a break. Use this time to calmly discuss the issue, listening to each other's perspectives. Focus on solving the problem rather than assigning blame. If you can't resolve the disagreement, consider ending the lesson and resuming when you've both had time to reflect. In some cases, it might be beneficial to seek the opinion of a professional driving instructor. Remember, the goal is to create a safe, competent driver, so always prioritize this over winning an argument.
