No. You couldn't have bought that without you. However logic doesn't integrate well with arguments with your wife. Devils advocate argument however, is you guys are a team so you can't work your job without her flexibility, especially when it comes to kids. It is her car, because she wanted it, but it's not rude to point out what that least half that car belongs to you too. You're the man however so best advice is to suck it up and don't drive it if she needs it.
