When two cars are stationary, opening a door and lightly hitting the other car usually causes no damage—at most, some paint might chip off or a minor dent might occur, but the door itself won't deform. Check the vehicle condition: Before driving, always inspect your vehicle to ensure it's in good condition. Avoid driving with potential hazards to guarantee safety on the road. Ensure seat belts are fastened: Always wear your seat belt while driving. Don't treat it as mere decoration or just for inspection purposes. In an accident, the seat belt might be the only thing that saves your life. Avoid fatigued driving: Never drive while fatigued. If you feel drowsy, find a safe place to rest. Stay focused while driving and avoid using your phone, as many accidents happen in an instant.

I've encountered this issue several times. Accidentally hitting the adjacent car when opening the door can indeed cause vehicle deformation. With a light touch and minimal force, it might only leave minor scratches or small dents. However, with stronger impact, door dents are quite common. This largely depends on the door material—for instance, older cars with thinner sheet metal are more susceptible, while newer vehicles using reinforced steel or aluminum have better crash resistance but can still deform. The angle of impact is also crucial—directly hitting the middle section of the other car's door panel significantly increases deformation risk. I've witnessed many such parking lot incidents where repairing minor dents proved costly and labor-intensive. My advice: always check surroundings before opening doors, especially in tight spaces—crack the door slightly to survey the area first. Developing this good habit can prevent many subsequent hassles and save considerable trouble.

My experience is: Don't underestimate the damage when opening a car door into the neighboring vehicle! Once, my friend hastily opened his car door and slammed it into the neighbor's car, leaving a large dent. The extent of deformation depends on the impact force: a light touch may only scratch the paint, while a strong impact can cause dents. Car doors are designed with energy-absorbing structures, but the materials—steel or plastic composites—can't withstand heavy impacts. Parking position also matters: opening a door in a narrow alley increases the force on the other side, making it easier to damage the internal frame. My advice is to leave space when parking and open the door slowly, stopping at about a palm's width to check. Prevention can save repair costs and avoid unpleasant situations. As I often say, caution ensures a long-lasting car—these small habits make for smoother journeys.

When opening a car door and hitting another vehicle, deformation is possible. With a light impact, it might only leave a shallow scratch; a slightly stronger force could cause a dent. Car doors are made of metal or reinforced plastic, which can deform or shift under pressure. Their structural design allows for some elasticity, but excessive force will cause deformation. Maintaining sufficient spacing when parking is key. If an incident occurs, first assess the damage to the other vehicle and address it promptly.
