My dad is a Pentecost. I'm an atheist. He knows this and it causes frequent arguments, but he hasn't disowned me...yet at least. My dad is in his 70's and also has really bad macular degeneration, which is making him go blind. There's nothing doctors can do for it right now. He can hardly see to drive, especially when it's dark but he drives to church on Sunday and Wednesday nights. He won't try to drive at night, unless it's an emergency, or church, because he realizes how dangerous it is. He's admitted to me that he has come close to nearly hitting people walking along the road at night and just the other night he almost hit a deer. He drives almost like a drunk man during the day, swerving over the road. At night, he can barely see the lines at all and the glare from other car lights coming at him temporarily blinds him and he says he just drives based on memory.

The rest of the family and I have tried to talk him out of driving at nights and offered to take him, but due to jobs and other obligations, we couldn't do it all the time like he wants. His church members have offered to also, but he will have nothing of it and is very stubborn about driving himself. I get the feeling the church members seem more concerned with him coming to their church than his own life and don't want to really pressure him into letting them drive him. His eye doctor didn't seem that concerned about it either and just told him to use his best judgement (I guess he's worried my dad will get mad and quit going to him), but unlike the doctor, I've personally seen his driving before and it's horrendous. The rest of the family is concerned, but has given up and seem to just have a "whatever" attitude about it. I'm seriously worried something bad is going to happen. I've told him that I'm afraid he's going to end up killing himself, or someone else, but he claims Jesus helps him to church and back and if he dies, he's ready for Heaven. I've asked him about what if he accidentally kills someone else on the road and he says, "Well, if they're a Christian, they'll go to Heaven." Hearing that from my own dad really hurts. To him, it's not his responsibility, it's Gods' and whatever happens is part of his "plan". He doesn't see a need in taking responsibility for his own life and the lives of others when it comes to going to church. It's like he sees it as his own personal test from God to see how faithful he is.

Even though I wish he didn't go, I'm not trying to force him into not going to church, but that's what he thinks this is about instead of actual concern for his life and others. Whenever I bring it up now he just claims I'm trying to tempt him away from the Lord. I don't know what else to do to get him to give it up and ask for a ride, or just stop going at nights. I have seriously thought about hiding his keys and calling someone to give him a ride, but I'm afraid this would just put an even bigger strain on our already strained relationship. I really don't know what I can do at this point, but I don't want to just sit back and wait for an bad accident to make him stop.

TL;DR: My dad has really bad eyesight, but won't stop driving himself to church at nights. He claims his faith in Jesus will help him get there and back without an accident. How can I convince him to give up driving and ask for rides?

[Update] So I decided to confront him again over it. I finally told him that if he didn't give it up, I was going to take away his keys. He told me that I couldn't do that because the car was his property and he'd call the cops, which again, I didn't want them to get involved in this mess and they probably would side with him. I suddenly had an idea pop in my head. So I said, "Fine, but what wasn't his property anymore was the Bible he gave me when I was a teenager." I told him that if he didn't stop, I was going to burn it. He thought I was bluffing, but when I got it and a lighter and started out to our trash pit, he realized I was dead serious. He then tried to claim that was his property too, but I pointed out that it had my name printed on the front of it :) Even though there are a shit load of Bibles in the world, this touched a nerve. He threatened to call the cops, but I said, "For what? Destroying my own property?" He realized there was only one way out of this for him and I got him to swear he would call someone to take him to church from now on and if I hear of him going on his own, I would still burn it.
