1. ①Leave both cars where they are in the lane until the police arrive and wait beside them
2. ②Since no one is hurt, both drivers simply drive off without a word
3. ③Turn on the hazard lights, record the location and damage with photos, then move the cars to a safe place such as the roadside and exchange personal details
4. ④Leave the cars in the middle of the lane and argue with the other driver over who is at fault
