I may have worded my reply too strongly, see another comment about "second set of eyes".
But this is dangerous. When I open a bottle in my car, I know that it's a more dangerous situation than usual, I pay more attention, choose the right moment and see that I finish drinking quickly.
A Tesla driver can easily fool himself into "everything's fine, let me sip from the bottle for sevetal minutes and maybe search through my audio CDs".
Does everyone else pull over to change the CD or take a sip of water?
