While it may seem unlikely, it is possible to hit a car and not be aware of it, especially in cases where the impact is minimal. Distractions, noise, or other factors can contribute to a driver not realizing they have caused damage to another vehicle. However, all drivers must remain vigilant and attentive while operating a vehicle. If you suspect that you may have been involved in a collision, it is important to stop and assess the situation. You should then take appropriate action, such as exchanging information with the other party or reporting the incident to the police.
