my previous car had an interesting issue, i would be driving along and all of a sudden all the warning lights would come on and the speedo/tach would stop working, sometimes the central locking would try to lock also, i kept taking it back to the dealer, everytime they checked even on a test drive, they found nothing, i told them that it sounded like a short somewhere as the issue was very random, but was shrugged off with the 'punters know nothing' look while smiling and saying "yes sir certainly sir, would sir like a coffee, this way to the waiting room sir" luckily they kept giving me a rental for nothing, so i didn't really care, but after a few months of this they had the car for nearly a week, they replaces the BCM which they thought was bad, they were about to throw in the towl and give me a new car, when the 'technician' saw some sparking by the firewall... oh my someone had forgotten to put in a grommet, and hence a couple of wires were shorting causing all the issues! they replaced the loom (under warranty) and i got my car back, it was mentioned in passing that it was what was suggested a few months before by me, but the subject was changed quick!
I bought a new car 2 months later, even though it suffered no problems after the fix...
i like having traction control abs and eba as well as a number of other safety features, while i never really have call to use them, (TC in the winter in chicago/midwest, though not nescassary, is very useful though it was fun to turn it all off in the parking lot and have a jolly good romp on the snow) brake assist scared the crap out of me when it engaged, a large truck decided he wanted to be where i am and pulled over, no signal (at highway speeds) i hit the brake quickly, not very hard but firmly (luckily there was no one riding my a$$ - yes, i did check first) and the car loses ALOT of speed real quick no skidding either. so while the best intention os to be fully aware of everything, sometimes you are caught by suprise, besides, without all the cool things and warnings and buttons to push you cannot pretend to be james bond in a traffic jam.
