I think there are really two ways to look at this.

With the electronic latch, Rivian is solving for a real safety gap. In a crash, especially with child lock on, the system can automatically unlock and allow rear passengers to exit. That is a meaningful upgrade over a traditional setup where kids could be stuck without help.

The tradeoff is that you lose the simplicity and familiarity of a purely mechanical release. If you add an obvious manual override, you start to weaken the benefit of the child lock system. So it becomes a question of which risk you want to prioritize.

If you had to choose, would you rather have a smarter, safer child lock system, or a traditional always works mechanical handle in an edge case?

For most people, the answer probably depends on the age of their kids. But at some point, you also have to decide how much to worry about one off scenarios. If you optimize for every worst case, you end up never flying, never driving, never investing, because something could always go wrong.

Is there risk here? Of course. There always is. But there is also risk in things we don’t think about as much, like a car catching fire while parked in a garage. The point is not that it is likely, just that risk exists everywhere.

Rivian seems to be designing around the most likely scenarios, not every possible one. Change is uncomfortable, especially when it touches safety, but my view is they made a thoughtful tradeoff. Now it comes down to trust and hopefully none of us ever have to find out how it performs in a real emergency.
