Not trying to be argumentative - but why is that interesting? Scooby is a simple L-shaped bar - the ride simply has a 'minimum closure' point - where the body of the car + the bar = rider secure. In these pictures, the bar is J-shaped, so while not going all the way back down to the ground (probably because its a tight fit there as it is), the J probably ensures the closure of the harness against the body of the ride vehicle, while suiting smaller bodies who might otherwise slide out of small gaps in the L harnesses that Scooby has...
Considering the ride track itself isn't changing (that we know of) this appears to be a project designed to ensure that all riders are properly secured as the current lapbar stops atop the biggest person's legs (mostly parents) leaving the child quite loosely held. This is perhaps what lead to the increase in height requirements - and hopefully with these individual restraints, this allows them to better secure the smaller kids who used to be able to ride this, so that the height limit can be reduced.
I see an increase in ride ops required due to harness checks on both sides. Hopefully they don't go down the Buzzsaw route and close one entire car to permit the op to crossover.
I know its been briefly mentioned somewhere previously, but how is RRRC the only one in the world with a height limit that high?
From Woodstock at Cedar (91cm) built a year before RRRC, to Hippogriff at USJ (built 2014) all of them that i can find are 91cm. RRRC is 110cm with an adult and 130 to ride alone, but historically it was 100cm, and i'm sure once upon a time it was 90cm also.
Like sure, aus regulations and all, but it just seems ridiculous - even moreso when spongebob isn't that high either.
