Why not? Some people can't work regularly for whatever reason and are on fixed incomes.
So I should just give you money - some random person I do not know. Why? The reason being is that if I am to give my money to someone - I am going to give it someone who needs it. Not because they want to get a driver's license. I am going to give it the family that needs a life saving bone marrow transplant for their daughter. That's seems much more important to the average person and an actual need than you getting driving lessons.
Why would I fund you? You would have to give a convincing reason why you cannot work or a really good reason why you would need the money. I gave you the example of the single mom. Her car died and she needed one to get to work. So the church got together and was able to get her a used car.
Now you just saying you cannot work regularly is not a reason - unless you are disabled or a some other really good reason. There are many people out there in need so you have to have a better reason to give money to you than say a single mother who is trying to feed her children or someone that needs life saving surgery.
Explain your story - it has to be good enough that people would actually feel that you need this money to survive.
My mom cannot work and is on a fixed income, but yet she does not expect you or anyone else to give her money. She lives off her income and what she was able to save because that is what she has. Why would I want to better you? And why can you not live of your fixed income?
