I haven’t read the report, but the news item made me wonder if that means we shouldn’t talk with passengers while driving. Why is talking on Bluetooth any more dangerous than talking to someone sitting next to you in the front seat?
In either case, it is certainly true that while driving you must keep focused on what you’re doing. Distractions can be hazardous, but ordinary conversation doesn’t have to be a distraction.
People have been talking while driving since they first started using automobiles.
