Nothing to do with speed or aggression or the utter laziness of most drivers.
Off on a tangent I know...
But modern cars:
Park themselves, because people have lost the ability to know where the extremities of their vehicle are, and as such cannot park it.
They have a camera to see hehind, because drivers are too lazy to turn round.
They have automatic lights because drivers are too thick to realise the light level has dropped and they can't see/bee seen.
They have automatic wipers to save the terminally lays from having to extend a finger and manually activate the wipers.
They have automatic gearboxes to save people from changing gear themselves.
They have cruise control to save people from actually having to use the other of their legs that DSG doesn't relegate to 'not required'.
They have ABS/ESP/TCS etc, which whilst being perfectly valid safety systems, they allow the stupid and the lazy to let the car sort out poorly judged applications of brakes, throttle and cornering ablilty.
They have tyre pressure warning systems that whils warn you of a ligitimate de-pressurising tyre, also allow the lazy to never check their tyre pressures,...and hence never bother checking the condition of their tyres.
Which allows the driver to make swift, relatively safe and speedy progress whilst completely insulated from all road conditions, oblivious to those round about them...and frees up their limiterd attention span to let them play with their touch screen in car media systems.
