"Using our phone" is a very vague thing. Those distractions surely aren't as dangerous as interacting with people and reading a phone. However some activities on the phone are less distracting than the ones I mentioned, and are less distracting than unlocking a phone without a thumbprint reader.
This is a new issue for me as I bought an iPhone 11 last night, but probably will take it back due to its unwieldy size and difficulty to unlock in certain situations.
