The question we should be asking is, like when ABS was fitted as standard on all cars by law, will drivers start driving even faster and more recklessly (e.g. driving as close as the technology permits or braking very late), leading to more accidents if you take into account system failures, unusual road conditions and other road users whose vehicles don't have this technology or it makes little difference (e.g. HGVs).

Tailgating, I believe, has got worse since I started driving in the early 1990s, especially on faster roads such as dual carriageways and motorways (particularly in bad weather/poor visibility). Too much technology such as this is making inherently bad drivers think they are good (or at least people think they are better drivers than they really are), and over-confidence is, in my view, very dangerous when applied to control of road vehicles. Everyone whould be capable of driving without the need for such 'driver aids', which should be used in case of an accident, not to push the limits of driving standards down.
