>The result? Sales dropped for those cars, no one wants to pay 50% more for insurance, and manufacturers quickly worked to fix the issue.

In all cases the margins were razor thin. Poorly equipped cars were stolen marginally more and likewise cost a trivial amount more to insure.

But personal new car buying is 500% driven by consumers using emotion driven logic to magnify tiny differences so sales dropped, somewhat, maybe. It's hard to separate this from the variable of older products and cheaper products generally selling less well than the new hotness. Column locks went on to become standard as OEMs refreshed product lines and did mid-life facelifts.
