Being able to use your phone to talk to people is not safety critical either. And yet, we make laws to lower the amount of physical interactions required with the phone while driving. Because people _do_ use them in ways that negatively impacts safety, both for themselves and other people on the road.
The question isn't whether or not the interface needs to be interacted with at times when it would be a safety issue. The question is whether or not the interface _will_ be interacted with in a way that would be a safety issue. And how much of a safety issue that is to _other_ people. And what better options there are to prevent those issues.
"People can use it responsibly" is not a viable strategy here, when the (many) bad actors injure and kill 3rd parties.
