I know it rarely happens but every incident is too much. How long will it take before all aircrafts are equipped with TCAS or a similar system ?

Is your car equipped with an automatic braking system? One of those that brake for you if you approach an obstacle and don't react. If not then why not?
Why isn't every car equipped with one of those as hundreds or maybe thousands of people die every day in ground traffic? The answer is money. Such systems are expensive and not everyone can afford them.
