My rear discs have done nearly 20000 miles and still bright and shiny. No grooves just a very slight lip on the edge.
I am still of the opinion that as I reverse into my drive, the brakes get a chance to operate in reverse thus cleaning off any collected crud.
I also have no problem with the handbrake holding.
As to good tech bad tech: I have been driving an 18 plate Ford and I am a little bemused ( absolutely terrified) of start stop. Keyless entry and starting ( luckily my EX Ishift has conditioned me to foot on brake to do anything) There is no jack nor spare wheel. A great big tv screen which does everything except boil a kettle and gongs that ring when ever you transgress any of the system.
This am on a BBC feature, a bit regarding keyless entry and starting. Many people in the states have died of carbon monoxide poisoning because they forgot to switch the engine off. Ford did introduce a safety device to switch the engine off after 30mins if the car was not driven. The first day, I drove the Ford, I stopped the engine but did not turn the ignition off. I opened the door to a very loud chime. As Jocko says give us straightfoward vehicle without all the silly bits that are there to attract the many. Completely off as subject over 50% have gone over to DAB radio it might well be that FM will be phased out. I looked at some DAB radios, why do you need a USB port on an alarmclock radio? yet another gee gaw. Yes I am a luddite!!!!!
