I think that it would be cool if every person who has a vehicle(new or old)has an option to buy a device(not yet invented)that automatically tells a person via voice what is exactly wrong with their vehicle.
That way no one will have to go to school to learn about cars if they constantly have car trouble, and it would knock out the possibility of getting ripped off from mechanics who are supposed to get their vehicles fixed, but get ripped off instead. The device would automatically be fool proof, stating things like, « Your car needs a new engine now », « You need a new timing belt », You need a new starter now and it will last one more week. »
That is what I am talking about.
