The 2in1 carrycot + car seat models are usually not large at all. There are two exceptions - the Cam carrycots, and the Inglesina carrycots, both of which can be used in the car with an auto kit. These Italian brands make large, spacious bassinet-car seats.
From your choices, all three are very small, limited to, realistically, up to 4 to 6 months of age, depending on the season and your child's weight and size.
Personally, I would not really want such a thing btwm ,a car seat is, in any case, a safer bet, but I understand that for regular very long rides this can be an advantage that is friendly for your child's spine. Perhaps also look into car seats inclinable even during the car ride - the Kiddy Evoluna line, or the Joie i-Level car seat.
