Re: What motivation car manufacturers ?
Would you buy the same model car if your previous vehicle had been stolen ?
Depends. If the theft was directly attributable to the manufacturer's sloppiness, then yes, probably. On the other hand, one may have a particular preference for exactly that type of car (because of size, economy, handling, loading capacity, ergonomy or whatever else), taking any downsides as they come.
 which in the EU may well get the manufacturer in a spot of trouble because of consumer protection laws.
