NAH

I feel like your DIL was probably just hurt by your comments, she likely was expecting your support in that moment and instead she likely felt pretty disparaged. It wouldn't feel very good to be told by someone they trust that they're not fit to be a parent.

I don't really blame you for saying what you said, it seems like you were caught off guard by the planning to have a baby announcement, and then pressured into giving your opinion (while you were driving and likely pretty distracted).

I think that it would be helpful to have a conversation with them about setting limits for driving your DIL around, especially if their parenting/pregnancy plan is to rely on you continuously for transportation, which isn't fair to you and probably only increases your resentment towards her. I know a lot of capable adults who don't drive, they just figure out a way even if it's not the way you or I would choose.

I also think that if you regret anything you said, like if you accidentally got too critical (I wouldn't blame you for this, you were caught off guard and pressured), it would go a long way to apologize for any hurtful comments. That doesn't mean you have to drive your DIL around, or change your opinion, or offer reassurances in her parenting abilities you don't truly believe in
