By that reasoning we would have metal spikes sticking out of the steering wheel pointing at the drivers chest. Things move on whether you like it or not. You continue driving your non abs, non reversing sensor, no seat belt car as long as you like while letting others use all the modern aids that they can get their hands on. It's a free country, in that respect at least. Apart from seat belts that is.
Oh, and from this Summer you will find all new cars with abs and within two years all will have tyre pressure monitors and nearly all will have reverse parking sensors. Go with the flow because they are here to stay.
