tyre pressure monitors are not necessary at all as anyone who follows the guidelines for basic maintenance and checks wont get caught out. They rarely stop a blowout as by the time the pressure rapidly changes its too late anyway.
Funnily enough when doing your driving test you are required to look in the direction you are travelling so at least 2 of the 3 mirrors you cant see....
ABS again isnt necessary if you know how to drive. Reliance on ABS is actually dangerous as im sure youll have seen plenty of times on icy or snowy roads as well as very water logged roads.
IMO most accidents are caused by poor driving and have very little to do with driver aids. Most of the problems you encounter on the roads are again caused by poor driving.
Driver aids cannot compensate for a poor level of driver skill in the first place. In fact with modern lazy humans, i suspect driver aids are more inclined to make the average driver lazier or complacent or less alert.
