I think it'd be really cool to have an official map of the IIHS testing area which includes the following tests inside the map. ( Underride + Side Guard Test, Side Impact, and Small Overlap ) + Maybe some things that aren't in the IIHS testing area but are in other testing areas for BMW which would contain the following ( Flip Ramp, Machine that slides a car into a sand pit sideways, and a sudden downgrade rollover ramp ). ~ Yes I know there is a modded IIHS Map ~
The OP already said he knows about the modded IIHS Crash Hall by Ghost, but he was talking about more stuff added in instead of simply an overlap test. Also, this exists aswell. Also a not-so-smooth flip ramp https://www.beamng.com/threads/nardelli-crash-test-cart.15809/
This?https://www.beamng.com/threads/iihs-safety-testing-works-flawlessly-with-0-4-0-6.10187/ I still have it installed, and it works perfectly fine
