The 70-year-old "Funny Girl" star said that the excursions give the couple the opportunity to get back to basics and enjoy the view as they cruise through the US in a truck bought specially for the long drives, reported Daily Star.
"I got on a lot of road trips with my husband, we bought a truck with a bench seat so you could sit next to each other. It's fun to get away. You close the door and it's just the two of you," Streisand said.
Ironically, Streisand stars in new comedy movie "The Guilt Trip", about an inventor who hits the road with his mother to sell his latest product, but she refused to embark on a real trek across America because she didn't want to stray too far from her lavish Malibu, California homes.
However, the singer-actress said that she isn't opposed to travelling to neighbouring states.
"I never went cross-country, no; I've been to Arizona, you stop and eat... Anywhere that's got good food," she said.
