I can do all that, too ... and haven’t had a conversation-related accident. But, I’ve seen near misses and almost-accidents, so that or was an “accident” that I wasn’t in an accident ... :-) ...
You see, the nature of an accident is that things can come out of nowhere and the more concentration you have, the better chance you have of preventing that accident. Now, many times I’ve been able to “catch it” in terms of things coming out of nowhere, because even while one is on “auto-pilot” there are things that cause you to “refocus” at that moment.
However, the reaction times are delayed and, it’s a matter of “chance” that you STILL have enough reaction time, when “refocusing” your attention to the “accident about to happen”. AND ALSO ... one must realize that sometimes you being able to avoid that accident, even while your attention wasn’t fully on the matter at hand - was related to the OTHER PERSON keeping watch and AVOIDING YOU ... :-) ...
My method is a “strategy” which deals with INCREASING CHANCES for avoiding accidents ... while I find the normal methodology for a lot of drivers is to say, “What can I do and not have accidents all the time?” ... LOL ... thus dramatically increasing their chances of an accident and dramatically lowering their available reaction times.
I think people should do EVERYTHING POSSIBLE to increase their ability to avoid accidents and to increase the margin they have for reaction time.
You’re just looking for an argument. I’m out.
