Its really awesome that you have that last drive memory - Honestly I think that those kinda-getting-lost-in-the-moment type memories are probably the greatest ever. Im sure your father felt you were as great a son as you felt about him as a father, so dont beat yourself up over his care. If you feel bad about it, its because you have a good sense of right and wrong - that means you turned out to be a good person, Celebrate that!!!You were a good son, and he was a good dad.
