HELP MAMAS!!! Babies first road trip

Any suggestions on how to prepare? And what to do if my baby doesn’t like being in the car seat? Is it okay to nurse him when he gets hungry while dad is driving (going to be sitting in the back with him). What if babies ears get clogged? (We are driving on mountains). I suffer from motion sickness, what if my baby has that as well? My son enjoys fruits so I guess I’ll bring some when he’s awake. I really hope he’s able to sleep and stay asleep for majority of the ride. It’s just a two hour trip there and back but we’ve been in quarantine for so long I don’t know how baby is going to react being in the car for so long!! If baby hates the carseat will I be forced to put him in my lap or just watch him cry his eyes out... I’m so nervous!!!!
