When anti-lock braking systems (ABS) were first introduced in premium cars, accidents increased initially for that sector owing to driver over-confidence. The same effect is again being seen with modern driving assist systems. Since large vehicles are especially safe for their occupants at low speeds, this has a pernicious effect on driver attention, consequently increasing casualty figures for other road users. Every year there are fewer victims of car accidents – but not among pedestrians, cyclists and other light vehicle users.
My driving instructor years ago: "The plain fact of the matter is if you replaced airbags with spring-loaded spikes that shoot out of the steering column, the streets would be far safer."
