Similar to your “door to door with minimal breaks” - as an American, a ten hour drive is the minimum it could take. Yes we should take breaks more seriously

For example, I say it’s a 14 hour drive to my brother’s house. That means I grab breakfast on my way out of town, stop for gas and fast food lunch (perhaps to go), stop for gas and fast food dinner, then get there 14 hours later. If you take more than minimal breaks, it’s up to you to do the math
