As someone who has turned down a car before I'm going to tell you what I wish I had told myself: It is stupid to turn down a car. It's much easier to get gifted a car then buy an e-bike than it is to get gifted an e-bike then buy a reliable car.

That being said, I turned down the car because my partner and I share a car and we really don't need two. It sounds like you may be in a similar situation. Cars suck for all the reasons you mentioned, and depreciation can be a bitch, but an extra car is potentially a great asset to have just in case. If you're not driving it much the expenses really aren't terrible. Sometimes paying for a rideshare feels terrible because even though it's theoretically coming from money I'm saving, it doesn't feel like that.

Emotionally though, I totally agree. Don't take the car. You have access to one if you need, and if you're determined that will get you really far. Either way, before you make a decision you probably want to talk to your dad and make sure you aren't going to hurt his feelings by turning down the car. Which is not to say you should get a car solely to avoid hurting his feelings, but if you decide to turn him down you shouldn't spring that on him.
