I don't take any of my snakes for car rides "just because". The only time they are in the car, is for a particular purpose - going to a snake show to be displayed or to the veterinarian, and that's it.
Never, EVER would they be allowed to be loose in the car, not safely secured in a snake bag.
Other than that - no - the snakes don't enjoy it, and I'd rather them be safe and secure in their enclosures, rather than taking them for meaningless (for them) car rides.
