The camera is better now, also you should give it a try and add hands on the steering wheel support, to make it work get the Support_HandsonWheel from another vehicle and place it on your ZIP file, and add hand models on your vehicle model, hands and hooks, the left ones are called lhand and lhook, the right ones are rhand, rhook, and just check some new vehicles that has been released lately since they use it, it can be really neat for those lego cars
Also change the namecheck.txt from Vehicle_LEGO_Small_Car to Vehicle_LEGO, the car won't show up in the add-ons list if I don't edit the namecheck like that
