I got nothing. For us, we discovered that if we time car trips around their bedtime or naptime, she cries a while and then conks out. Then when we reach our destination, we take her out and put her in an adjustable lay-flat stroller (if outside) or to bed (if home). The process of getting her to conk out while we drive? Just pure grit, endurance, and lots of singing lullabies, which may simply be correlated, rather than causative. Sometimes it takes a while. :(
