I would not drive in a car/truck/suv alone or with someone, without a kitty being in a carrier. Safetly reasons for both of you. If Mina were to get spooked and jump suddenly into your lap, your going to loose control of the vehicle.

Mina will adjust to being in a carrier. All cats pitch a fit for a little while until they figure out that they aren't going to be let out. Usually what happens is they wear themselves out meowing at top of their lungs and lay down and go to sleep.

The potential loss of two lives isn't worth the risk without a kitty in carrier.
