I also have a MINI with lane keeping assist and collision avoidance braking. I don’t switch them off. I am not a police qualified driver but I have received two “perfect” IAM driving assessments from a former police driving instructor, who claimed I was the only person he’d ever given that to. Anyway, I leave the systems on but don’t rely on them. The lane assist occasionally vibrates the steering wheel but when it does it’s not a surprise to me, I am expecting it. I’ve never had the autonomous braking activate.
I consider them as a copilot, not a nanny. One day it might spot something I missed, but so far it has been a background system that has had nothing to actually do. I’m not so arrogant in my driving abilities that I believe I can catch everything forever. If anything did happen and it was found that I had disabled safety features, what then of the legal or insurance consequences?
A sensible approach imo.
I leave all safety systems on - most cannot be over-ridden anyway and the few that can don't bother me.
All the safety systems are designed to cater for human fallibility and, like it or not, no one who drives never makes an error of judgement or maintains 100% concentration at all times. Anyone who thinks they do is deluding themselves. The vast majority of lapses result in zero consequence but many serious incidents start with a small error compounding into one that becomes catastrophic.
Only a few weeks ago I had this conversation with a friend who is adamant that he can react faster than eg crash detection systems. Ridiculous. NCAP testing shows that an automated system will detect and initiate a complex series of evasive and protective actions before the human brain has even registered a potential problem, let alone do anything about it.
I'm no expert on all the processes activated during a crash incident so I may have missed something in this list that I rattled off to my friend:
Sensors monitoring state prior to incident will include vehicle speed, braking situation ie on or off, vehicle stability and power distribution to wheels, speed related steering input sensitivity, distance from vehicle in front, closing (or the opposite) speed to the vehicle in front etc. A competent driver will be doing similar, but on the other hand cannot know some of the listed parameters, nor have the same degree of accuracy on those they can determine.
So, in an imminent collision situation a well-equipped vehicle will calculate all appropriate parameters and take action. Roughly this will consist of applying brakes to pre-heat discs, power to wheels is redistributed, electronic stability control maintains optimum vehicle 'posture' and road positioning, seatbelts are pretensioned, airbags are checked and brought to a state of readiness, all open windows are closed.
If a crash is unavoidable then ABS and brake boost kicks in, some cars are are also equipped to undertake directional avoidance manouvres, airbags are deployed, the fuel system is shut down, hazard lights initiated, handbrake is applied when the car stops moving, vehicle location is evaluated and SOS call initiated.
My friend did not even know about many of these processes yet still insisted he could 'beat the car'.
As I said, I am no expert, and I may have sequence order wrong etc but to my mind there is an impressive amount of technology at work in situations where the 'chips are down' so to speak that wiil either reduce injuries, or even save the lives, of the occupants of a modern car.
