Car issues

I’m 16 and I took my driving test yesterday. Luckily I passed but I won’t be able to get my license until I’m 16 1/2 or until I take a 6 hour course with an instructor which sucks. Anyway, I got my permit obviously a year ago and my father said he would give me his car because he had 2. Well 6 months into my permit I asked my father if I was still gonna get his car and his answer changed to “I don’t know.” So I decided I wasn’t going to wait to see so I got a job and I love working for my money. Fast forward to now, I asked my father about the car and he says no because I got a job. Me and my mother asked him if he would at least help my family with a little bit of money to get a car and he said no. Now my fathers side of the family has never done anything for me; no gifts for my birthday, holidays just absolutely nothing for me. Well my father is upset that I can’t see him on the weekends because I see every 2 weeks and now that I’m working, it’s harder to see him with my schedule. When I told him I wanted to work to earn my own my money he said, “you’re going to be working for another 60 years, why start now?” Which I responded to that with, “because I want my own money. I don’t want to have to wait to get child support every month and because you backed out on us with a car.”

I understand he doesn’t HAVE to help me and that my mother and stepfather would help me because they want me to drive myself to work and school but I mean I see it as unfair. I’m his only child and he doesn’t seem interested in being in my life anymore. I’m not sure if I should just cut him off because of this car thing which seems petty but I mean this is a huge milestone in my life that he’s deciding not to be apart of. My father is a very stubborn person and no matter what you say or what you think and mention, he’s not going to change his mind as his ways.
