The Tesla Cybertruck received a lot of flak after owners reported that the electrically operated frunk lacked adequate anti-pinch protection. Even after Tesla improved this feature with the latest software update, people complained about their fingers being crushed. However, as Rivian owners got the same curiosity, they discovered that their beloved truck was no better in this regard.
The Cybertruck owners were dying to get their hands on one of Tesla's electric trucks, but when they did, they discovered that it lacked many features, including some related to safety. While it's possible to live without Autopilot and FSD, some found that Overheat Cabin protection was also missing, and locking differentials were not working. Those issues were solved with the latest update, but people were still unhappy. After some discovered that the anti-pinch protection of the Cybertruck's frunk was lacking, we've seen many complaints.
In January, one of the early Cybertruck owners risked his own hand to show that the frunk's anti-pinch protection was far from satisfactory. Tesla used a resistance sensor in the frunk's motor to determine if something was in the way, which is not such a good detection method when different parts of the frunk do not offer the same resistance. As physics taught us, the closer we are to the hinges, the higher the force, so the resistance is much lower, thus failing to trigger the sensor.
As a result, the Cybertruck's frunk would react if it encountered a significant obstacle at the front, but it would crush softer objects on the sides, fingers included. Tesla acknowledged this and increased the sensitivity of the anti-pinch protection to better react to soft objects on the sides. However, people noticed that fingers can still be crushed if they repeat the experiment. That's because the Cybertruck is designed to increase the clamping force with each subsequent close attempt.
Following these Cybertruck experiments, people tried to do the same with the Rivian R1T's frunk. If you recall, in one of the early experiments conducted by out of Spec Reviews, the Rivian was much better at the "carrot test." However, when people tried to replicate the experiment on the Rivian R1T, they were surprised to see that the EV startup wasn't much better than Tesla in this regard.
Specifically, some noticed that the frunk would stop closing when the object was placed on the sides but disregard it if it was closer to the front. Some explained this happened because the optical anti-pinch sensor doesn't extend to the front. However, some noticed that their truck reacted as it should to the object interference. For a while, some believed that newer trucks had better protection, although it was revealed that something else was going on.
It appears that Rivian, just like Tesla, would increase the clamping force with each close attempt. Since most people started experimenting at the frunk's edges, they probably got toward the front on the third or fourth attempt. This made their carrots (some used celery, actually) suffer. However, this proves that engineers from different companies think in a similar fashion, leaving owners in charge of their own (and their children's) limb protection.

So… ehh… watch your fingers
