Sam & Loki have matching seats next to each other in the back. I want to get the My Buddy, but they do fine now so I don't need it.
ANYWAY - Sam did whine at first. It took probably 4 or 5 trips until she stopped, and it helps if she's tired. She prefers a lap, but she tolerates her car seat and she does much better if Loki is also in the car. After a few minutes she just falls asleep. If she was in a console seat she would fight to get out of it to sit on my lap. She's better off in back where getting out of her seat just means she has to sit next to Loki.
Loki got used to his seat when he was a puppy. A good blanket and a bully stick is all he needs. He prefers his seat to a lap. To him, a car ride is just a good excuse to take a nap.
