Electrical short and potential for fires in the cars will be always an issue.
Compare car electrical system with houses.
Car has more circuits and fuses than 6 bedrooms mansion.
So it is not avoiding potential shorts, but protecting the car from results that plays main role.
On Mercedes when something shorts, the fuse blows - end of the story.
On my Ford truck parked for 2 weeks shorted wiper end switch was smoking for several minutes while my wife was making frenzy phone calls. By the time 30 amp fuse burned, the whole plastic housing of wiper gears was badly melted. Would that be more combustible plastic, the truck would go with it and that what happens to them on cruise control brake switch, that was originally hardwired to the system with no shut off switch and no fuse.
So the linked accident is rare and as mentioned - turning everything off should stop the fire. If you don't stop and get fuel lane ruptured, than the car is gonner.
