Absolutely never, well there’s one exception:
I use the interactive activity of driving to clear my head.
I savor every sound, every little creak from the Teflon impregnated urethane bushings, every sensation from the power delete steering rack, the ridiculously stiff tires, the audible snap from the shifter. The deleted sound deadening material. The bare metal and exposed wiring in the rear hatch.
The minimalist Polk Audio system is rarely on.
There’s always something that should be looked out for. Driving is one decision right after another. Am I going to shift down or remain in third? That depends on what I see going on multiple cars ahead of me.
Why am I still in third and not fourth? Because the longer I wait to shift the more information I collect as to what is the appropriate selection. Oh, and the SOUND.
Why don’t I smoke in my car? Don’t want the smell? No, Don’t want burn marks on the A pillar cover? No.
Because it would be redundant and wasteful. I’ll take the sensation of driving over that offered by smoking any day of the week.
The exception: Autopilot? No, rather in the zone on highway trips. “The Narcotic Suite” by the Prodigy is playing, loud. Caffeine working it’s alkaloid magic between my synapses…
Scan ahead, check the dials, check mirrors, signal, drop ratios, pass, check mirrors, shift back to right, repeat. Second nature.
