you took it personally for reasons only you could know.
I took it personally because you said "Imagine this guy is a commercial airline pilot." (emphasis mine). Personal insult aside, you're comparing apples to oranges. Of course piloting an airplane for the first time carries more risk, and thus different training requirements and safety precautions, from driving a car on a previously travelled route.
You taking your eyes off the road to fiddle with a GPS could, at most, kill the handful of people around you
Which is why I used the voice control feature until it proved useless and then had the passenger enter it manually. I stated that very clearly in my original post. My eyes were on the road the whole time.
You need to 'chill out' on the emotional responses. FYI, that wasn't an insult
It was an insult. Your statement may have been directed at the rest of the Slashdot community instead of directed toward me, but the content was insulting to me. If you didn't intend on a little bit of insult, you would have said something like "Imagine this approach to piloting a commercial flight". Yes it is subtle and I didn't take a huge offense since it was far from the worst thing someone has said about me, but I felt it was worth calling you out on.
