I think the fact that you're asking shows that you actually have an issue with it yourself. But like Rugglesby said, 'You do what you gotta do'. I'm sure when the time comes and you feel that you need to make a change to the situation you will. Until then try being ok with it

I lived in cars for a few years. It's ok and makes you a bit creative, but it can become a psychological issue after a while.

I didn't do Uber, but back when I was a teen, I had a permanent job, and a car with a loan, rent around where I worked was out of my range so I lived in my car.
My foster son travels fro his business, he sleeps in his van along with his stock,
when he comes back here he stays in bed for hours every morning and enjoys the hot showers to the max to make up for it.
You do what you gotta do.

no

Nothing wrong with sleeping in your car, just make sure it doesn't develop a funky smell or get that lived in look about it. You must have comfortable seats to sleep in your car on a regular basis, those few ocassions where I have spent the night in my car always left me with a killer back ache and feeling groggy.

I have a good friend who left his pro job to drive Uber around Boston. Don't think he does overnites.

I do AirBnB now and don't do hotels. Its better and half the price.
