"Can you drive a car for free (for 5 - 8 hours) until you decide that's the car you want to buy?" Yes. It's called a test drive. I think the longest I've seen is a free 48 hour test drive with an online e dealership, but free all day test drives are the norm in the UK. Similarly most lawyers will give you a free consultation. I think you have a highly distorted view of reality, how other professions operate, and of your own worth.
