I'm sure it can roll, 330MPH backwards is what it took to get the stock D series to blowover, that's without downforce from the rear spoiler, meaning if said spoiler is set up right the truck will blowover at 180-200MPH, I made a video on it
Well asuming the roof and hood flaps work properly then it probably is unlikley it will blowover unless perhaps the car was traveling into a headwind before it spun out. However the flaps will be removable so who knows
I believe its been talked about before, with the mention of a hard enough impact, but hopefully it could be possible for the truck to rip apart to almost bare bones. For example, Jeff Bodine's Wreck.
do you want it done quickly or do you want it done well? --- Post updated --- its not going to die, i have put far to many hours into this to just give up --- Post updated --- very nice, try adding a couple of smaller logos to fill in the gaps, real nascar liveries are covered in lots of tiny logos --- Post updated --- i have thought about that, unfortunately beamng's physics don't cope well when things beg ripped apart. so the the main chassis will remain in one piece even in the biggest crashes. it will still be able to be dented pretty badly. all of the body panels will be able to be torn off individually. the radiator duct, radiator, engine and transmission can be ripped out as well. so you can still do some serious damage but don't expect to be able to tear off the whole front end.
What @matty1080 said above, all the body panels will be able to be detached but as for the chassis it would require a huge amount of work for something that isn't worth it. Not to mention it's also something that might very well negatively impact handling as the chassis could flex and wobble more than it should.
