Fair enough. Slight exaggeration. Like others have said here, from the history of the dog a cage is not always appropriate or the solution.
I certainly would not want to leave Rona in the car for 12 hours when BF offer the excellent service of a pet-friendly cabin. She is young and (most of the time) astonishingly well-behaved for a terrier. She is better in our company than being on her own for that length of time, where she would get bored and start to chew.
No 12 hours is way too long. But providing there’s no known history of an animal being abused with a cage (nor should it be used as punishment by a new owner) cages are a godsend and we’ve never had a dog (and we’ve had a lot, currently two ex rescues in stock out of four!) that didn’t thrive with them. You leave them open most of the time and also chuck a blanket over the top and they see it as a place of safety. Ours will dive in there the minute any thunder starts 
I couldn’t imagine leaving our Tommy for 12 hours, he’d be completely thrown.
I think you mentioned on another thread that you suffer from seasickness. OH isn’t a good sailor either but he discovered Seabands bracelets, I don’t know if you’ve come across them? They work on acupressure, so no pills involved. Amazon and others have cheaper versions.
Used them for years. 
A godsend on aeroplanes when I was travelling for business and didn’t want to take pills and then struggle to stay awake in meetings.
On boats I need the pills as well, so night time travel is ideal. As a child I got seasick on swings and in a rowing boat on the Wey.
You must have very sensitive ears.
My OH got seasick in Brighton aquarium/seaworld, and then again on Brighton pier
I shouldn’t laugh! 
But I bet you did !
Probably wasn’t the first person to throw up there…
