Flight of Fear. I actually quite like the ride even though it's gotten pretty shaky with age. The bulky lap bars on seats that are much too close to the floor create a cramped, uncomfortable ride position for anyone in posession of legs. The shin guards are so restrictive that your feet have to be in precisely the right place, but depending on the row, the vehicle is so cramped that there isn't actually space on the floor for an ordinary shoe in that position. I remember having one ride with my left foot pinned quite uncomfortably beneath the center of the shin guard, because my shoe was too long and wide to fit correctly next to the wheel well. Plus having seatbelts that ride hosts must buckle to the outside of the train is just the dumbest possible design. It makes load times slow, increasing the likelihood of getting stapled by a rushed ride host under pressure to meet their dispatch interval.
So yeah, basically any other kind of lapbar would improve the ride.
