This means that JATO and ram plow will e automatically placed in proper places on them, you no longer have to use the Tuning tab. Note that this doesn't work on mod cars, you still have to adjust it yourself on them. Also most roof accesories from the mod are not supported, you still have to position them manually.
Additionally, the messy attachment selection has been really simplified:...
Added "infinite fuel" options for JATO rockets, both the side and the roof ones. This was requested by some people. Selectable in the rocket sub-slots where the attachment nodes are. Technically it's not infinite but 99999999999999999999999999999L should be enough lol.
Added more light bars: amber, red and blue. Available in the roof accesory slot. Note that they spawn higher than the police one as they are meant to be used on larger vehicles.
