Yeah there are always levels of risk we as a society have chosen to allow. My thinking was along the lines of how to self-regulate these imports of cars that do not follow the common safety standards our society has chosen if they are forced upon us by trade agreements or well-intentioned loopholes.

("murder" is a bit an extreme reaction but the more realistic idea may be to make harsher judgements the more pointlessly large and dangerous the vehicle is)

Easier might be to just not give exemptions when public safety is the tradeoff?
