I drove most of the length of the country this week, on my own, with nothing to do but watch the lane markings go by. I'd loaded up a stack of podcasts the night before, which is the kind of small bit of preparation that pays off enormously about ninety minutes in, when the radio has run out of anything worth hearing and you're somewhere grey near a service station you'll forget by tomorrow.
There's a particular sort of attention a long drive demands. Enough that you can't read or properly think, not enough that your whole brain is occupied. Podcasts fit that gap exactly. I went deep into a back catalogue I'd been meaning to get to for ages, the sort of slow, talky technical interviews that would bore me senseless at a desk but were perfect company at seventy miles an hour with the cruise control on.
The odd thing is how much sticks. I solved a problem I'd been stuck on for a fortnight somewhere around junction 20, not because anyone on the podcast mentioned it, but because the half-distraction let the back of my mind have a go at it without me leaning over its shoulder. By the time I pulled in I had the answer and a flat phone battery.
Anyway. The coffee at the far end was terrible and I'd do the whole thing again tomorrow. Sometimes the best debugging environment is a car and four hours of nothing.
