It’s fundamentally the same imo. I have a 2016 X. Sensors will not solve every situation, but overall I love the FWD. Whlie people can name tons of situations FWD might have issues like street signs, the same can be said for regular doors. It’s much easier to get kids in and out of FWD than regular doors when parked next to another car. It’s way easier to get kids into our X than our 3 in all situations. If you park next to the curb to close or to a mailbox or street sign in a regular door and swing your door open, it’s going to hit that too. Instead of getting in or out simulataneously, I pre-open the doors with the remote as I’m walking up.. so having the doors powered is awesome. Same for the drivers side door, i can get in, put my coffee and phone down while pressing the brake to shut that door, so there are other ways to save time.
Overall the FWD have been excellent. I do step out of the car to check opening positions, but I have a no problems with that. I’d do that in many parking garages anyhow if I’m parking near posts or walls and my kids are getting out. It’s worth the “inconvenience” i suppose of checking opening positions of the door compared to squeezing my kids out of our 3 when we take that and park next to other cars. I would admit Sliding doors would have worked just as well, but even after 3 years owning the car, I still think the FWD are an engineering marvel.
