I think you missed their point. Usually this discussion involves taking a trip with an older car. Their point is that there is no more likelihood of failure on a long trip than there is on multiple short trips that add up to the longer trip.
The risk of failure always adds an element of excitement to the trip. I am always amused by these calls as I have a long history of taking long trips in cars that are way older and have a lot more miles on them, and I never give it a second thought, and so far, so good.
My riskiest trip was in a 61 Fiat Cabriolet. That was the forerunner to the Spyder. It had a history of blowing head gaskets about every 600 miles and on a couple occasions, doing even more damage. Anyway I went home on leave with the intent of driving the car back to my next duty station and I found the engine in pieces and all the required new parts at the parts house waiting for me to pick them up and pay for them, courtesy of my brother.
I put the engine back together and proceeded to take a 2000 mile cross country trip. It was a very exciting and memorable trip to say the least, I should have kept a diary. Blew the engine about an hour after arriving at my duty station. Got it running again, took a few local drives with it and the flywheel came off. That was the last time I drove it.
Had I known what a Belville washer was at the time, I may not have had as much trouble with it.
