Why are you sleeping in your car for long trips? :)
Perhaps buying a $60k+ car isn't the best idea if that means you can't afford a hotel room occasionally.
My uncle bought a Tesla 3 (coincidentally, to replace his 20-year-old totalled Jetta) because he needs to drive several hours to the office a few times a month for 2-3 days at a time, and the silent climate control and flat trunk floor means he can cheaply and comfortably spend the night in his car rather than driving 3hr back home or renting a hotel room. It is also much cheaper to operate.
I disagree. In my opinion if you can't afford to do that a few times per year without financial concern then you have no business spending $60k+ on a car. Having to sleep in your expensive car just so you can afford a vacation is ridiculous. There are much cheaper alternatives that won't force you to sacrifice other aspects of your life, such as your $2000 car.
I'm not even going to comment on your uncle's situation. Let's just say I would be working somewhere else if I had to resort to that.
I think it's more about Tesla owners becoming obsessed with their car, it's a strange group of people.
After driving a few hours, they only thing a normal person would want to do is get out of the seat, walk a bit, take a shower.
It's like when you were a kid and got your first walkman, you would take it anywhere with you, while eating, sleeping, even in the shower if possible.
Many people with money spend huge amounts on some things but can be penny-pinchers in other areas.
