I could believe it about the other things, but I really don't see how backup cameras fit in that list
Intelligent speed adaptation solutions are also very interesting, especially the closed type. I live in a country where the highway speed limit was raised from 110 to 130kph so that drivers going up to 180kph don't get their drivers license suspended and vehicle impounded and are just slapped with a fine. I kid you not.
Driving the speed limit is als frowned upon by many fellow drivers. It's so bad that the government has started to put physical barriers between the lines to prevent illegal overtaking on several high risk two-lane roads because so many people die due to head-on collisions that it starts to pose a problem with the public...
They seem outdated, even 20-30 year old cars are stable enough on the road to go 80-100km/h instead of 50. Germany has shown that driving as fast as the car can go is not the main cause for car accidents.
With some exceptions where I think they're doing something good, like dangerous curves, they are mostly used by police to make money for the city/government.
