The GT Hyperion doesn't have a working steering wheel, it's wheel also looks different from the others too.
Weird because it's the same wheel and the steering animation is working for me, maybe you have the outdated Hyperion, also there is a car driving around on RTB, you will might see him soon, also I made a few updates on the Volks Cross, Rally and Police variants

Cross and Rally are taller, and the Rally have a stripe

I added two exhausts for the Rally and a Wheel on the back of the Cross to make it more off-road looking

The police variant have a more detailed interior with radio and a protection between the front and the back seats like the police cars have
