FLU: We bought a mini-van for the family. Maybe it doesn’t have the safety you are looking for but the design makes perfect sense, the large sliding doors on both sides especially. Maybe there is an SUV with sliding doors? I imagine we would have dinged 50 cars if it were not for the sliding doors. 3 kids can sit on one bench so we have room for grammy an pop pop. We remove one bench for trips and have lots of room for stuff.
