Less than 26 hours from New York to Redondo Beach, and he did it solo. That would be averaging over a hundred miles an hour, I think.
That’s the sort of thing I might have tried when I was younger and stupider. I did do a 24-hour drive thirty years ago, but not cross country. I started out in Reno, drove up into northern California, decided to go up and see Crater Lake in Oregon (which I’d never done), then came back down I-5. By the time I got to the Bay area, I decided there was no need to stop for hotel, since it was only another five hours to LA.
Seeing lots of stories in comments, so here’s one more, my funnest non-stop. I was about to graduate, and driving out to California in late August to do some job hunting. On US 40 in Colorado, somewhere near Steamboat, I saw a young woman hitchhiking. I of course picked her up, to prevent someone less…scrupulous than me from doing so (of course, I didn’t consider the possibility that she was herself a serial killer). It turned out that she was headed to San Francisco to see her boyfriend who was sick in the hospital.
I had been planning to stop in Salt Lake for the night, but she was in a hurry to get there, and knew how to drive a stick, so she drove through the night across Utah and Nevada while I slept. At daybreak we were in Hawthorne (Nevada, not California), and headed from there over Tioga Pass into Yosemite. We stopped by an alpine lake in the high country and had a picnic lunch, then headed down into Yosemite Valley, then down through Gold Country, across the San Joaquin and into the city. When we got there, she found a pay phone, and it turned out he was out of the hospital. I dropped her off in a parking lot where he was waiting for her, bid her farewell, and headed down to Mountain View, where there was a thriving spacer community based at Ames.
