As with too many OEMs...wait, wait, wait...till maiming and/or deaths occur... Decisions by bean counter management...not engineering
Look up windtunnel images of vehicles and note that there is a negative zone underneath all vehicles moving through the air...that draws exhaust underneath that travels up to the front of the vehicle
Then if there is a hole somewhere and the designed in airflow metrics of all vehicle cabins will draw in that exhaust air
Now if sitting still, then another matter
Also note that rear hatch that goes down to the bumper area has to be sealed VERY WELL. After a rear end accident, mini vans are at risk of drawing in exhaust
Look up vehicle air flow in windtunnels....
Here is good one... :B

Seriously now...but couldn't find ones showing the undercarriage and that the reverse flow running backwards underneath the vehicle
