I'm sorry, but if you're dumb enough to ride in the trunk of a car, you deserve to be removed from the gene pool.
Trunk of a car, back of a pickup, bucket of a front end loader and on top of a flatbed trailer. Had 10 people in my '69 Impala for and extended road trip. Been there done all of that.
But not at 140km\h. The driver is the idiot.
You need to have respect for the numbers on your speedometer. Not that I've never travelled that fast, I've gone quite a bit faster in my youth. But not with a carload of people and not in traffic.
I'm not condoning any of this, just saying it can be done with relative safety.
I would hold the driver responsible. No one else.
