Aspects like whether it fits in the car’s cupholder, whether it is easy to handle and doesn’t leak, and whether it keeps the coffee hot/cold long enough are more important. When it comes to coffee mugs for travel, personal, emblazoned mugs and brands are pretty much secondary.
It ensures that you actually have your perfectly-made coffee, and don’t have to dump it when you get to your destination because it’s gone cold or watery.

Jocelyn Ivanov, MIT, Drinking fountains: the past and future of free public water in the United States, September 29, 2015 Wesley Johnson, cryogenics research engineer at NASA’s Glenn Research Center in Cleveland, email interview, August 22, 2018 So, “the copper liner needs to be: polished, installed in a vacuum, and done so in a manner that limits the amount of oxidation of the metal prior to pulling the vacuum.” “The main benefit of copper is that when it is polished, it is much more reflective of radiation heat transfer,” Johnson explained. But it works only under a set of specific circumstances. And copper can work to stop that last method of heat loss. “This leaves only radiation heat transfer between the walls,” Johnson said. A double-walled bottle already stops solid conduction, and a vacuum-insulated bottle stops gaseous convection. It could work, and as Wesley Johnson, a cryogenics research engineer at NASA’s Glenn Research Center in Cleveland, explained, “For spacecraft, we often use a similar technique for insulation.” The theory behind using copper in insulation (despite its being an excellent conductor normally) is based on the fact that heat transfers through three forms: solid conduction, gaseous convection, and radiation, Johnson told us. Sometimes manufacturers make bottles with copper linings in an attempt to keep the contents even hotter or colder.
