If airplanes are built to last 30 to 20 years, why not cars?

27. what is the purpose of your idea?

what is it you want to do?

do you want people to save money on cars or do you want them to spend more on them?

you seem to be offering contradictory ideas on that.

first, save money by keeping cars 20-30 years (many, many people do just that already)

second, be required to add ABS, air bags, etc. to an old car, or it will be illegal to drive it (that would cost a lot and end up pushing people to buy newer cars every time a safety regulation is added to new vehicles where retrofit of old ones is not feasible).

so your point seems to be that cars aren't kept long enough and your secondary point is to create a regulation that would end up having people replace cars even sooner than they already do.

as usual, your idea starts out half baked and somehow moments later you've burned it beyond recognition.

but at least you aren't complaining about the children who will be paying your social security and Medicare when you get old.
