Which of the following is true regarding mechanical issues and their relation to collisions?

The assertion that mechanical issues are estimated to cause around 0.5 to 1% of all collisions accurately reflects research findings on the causes of car accidents. Mechanical failures can include problems such as brake malfunctions, tire blowouts, or engine failures. While these issues can indeed contribute to accidents, statistics indicate that they are not a primary cause compared to other factors such as driver error, distraction, or speeding. This limited percentage underscores the importance of regular vehicle maintenance while also highlighting that the vast majority of collisions stem from human factors rather than mechanical failures.

Other choices propose that mechanical issues either cause the majority of collisions, are a leading factor in accidents, or imply no connection to driver performance, which contradicts established data on collision causes. While mechanical issues can impact the function of a vehicle, they are typically not the predominant reason for accidents, reinforcing the accuracy of the estimated percentage.
