From time to time you will see someone with a Falcon Wing Door issue, but they overall work pretty well.
Reminds me when Dad would never order a car with power windows because "that was just something else to go wrong"
It has many advantages, such as making entry and egress easier, installing kid seats easier, sheltering occupants from rain when open etc.
Downsides is that they are powered, can pinch fingers, can hit you on the head etc. Gotta be careful with them, expecially if it is something new that you are not used to.
For me they have been fantastic. Far easier to use than regular doors, and delightful to use. Love being able to push a button to let passengers enter the car, then show them where the buttons are to operated themselves.
