Tesla FSD was forced to stop by a floating plastic bag while driving, and was rear-ended by a truck from behind.

Abstract:

Recently, some Chinese people suddenly encountered danger while using Tesla FSD abroad. The reason for this can be attributed to a plastic bag. Judging from the video he posted, he turned on the FSD and drove normally that day.

The traffic in front was slow. Suddenly a blue plastic bag floated from the opposite lane. By coincidence, it rolled down to the front of his car. The FSD immediately braked.

At this moment, a truck behind the Tesla failed to brake quickly and plowed up, causing a rear-end collision.

The Tesla owner stated that

he believed that FSD accounted for 80% of the responsibility for the accident, and the rear-end of his truck accounted for 20%. "The other party did not brake in time, maybe he was a little distracted."

However, he also highly praised the safety of Tesla, saying that even if it was rear-ended, there was almost no damage to the rear of his car, that is, the license plate and bracket were dented. Of course, this was also related to the slow speed of the car behind him.

The reason why Tesla FSD cannot accurately identify plastic bags

is because it uses a purely visual solution, relying on cameras to collect images and neural networks to identify objects. Plastic bags floating on the road are a typical "long tail problem" and cannot be stably recognized every time

The characteristics of the bags floating on the road are extremely unstable. Some are transparent and some are colored. They will deform all the time after being blown by the wind. It is difficult to match the standard object samples in the model training library. Humans can judge that there is no danger and directly press over them. However, AI does not have this kind of physical common sense and can only rely on image features to make classification judgments and give priority to braking.

In fact, it is not just FSD.

Plastic bags can be said to be a major problem faced by assisted driving groups. Excellent solutions may trigger detours, but most will also choose to stop directly
