Airbags and crash test dummies

How about deployable airbags in the vehicles?

"Loadable" Crash test dummies with adjustable individual weights. (eg. from skinny to obece).
With the option to buckle and unbuckle their seatbelts (2-point, 3-point and 5-point racing harness?).

Also would be nice to add cargo from the menu, like fill the trunk with 300kg of batteries, load van with 2000kg of concrete blocks etc. Also the trailers.
With the option of different levels of securing: No securing, some securing, heavy securing and welded/bolted.

And a final must have: 1980s Monster truck with some weight to it so you kan realy crush the cars

 

This has been suggested tons of times

 

oh, late as usual :/
