So do all these innovations mean that there will be less cars totalled and less junk cars? Generally, yes. If a car is safer on the road and has technologies to keep drivers from causing accidents, there will be less damaging collisions and less cars sent to salvage yards.

Salvage yards give better rates to newer cars with usable parts because they can sell those parts to repair shops or car dealers. If the number of new junked cars goes down, the amount of parts to sell will also drop, possibly creating a higher demand for a scare product. Those selling their junked car may be able to get more than usual if the computer systems in the vehicle are still in good shape. Scrap yard enthusiasts who comb for parts for their own vehicles or to sell themselves may have a harder time finding valuable parts at typical low prices.
