Just bag her, she'll be fine. I've taken my snakes on 1.5 hour drives to my friend's place to get sexed, and they never had a problem. Just keep the temperature in mind, and either bag them and then put them in a smallish tub, or have a friend in the car to hold them, so they don't slide around a lot.
Do the tub AND a pillowcase ahaha thank god I did when I took my boy to the vet(45 mins away). He peed on the wayin >_>
