More Yaris Mk4 Safety Systems fun!

[Cyker]

So in addition to over-zealously flashing up the brake warning, randomly stranding me in the middle of T-junctions because it thinks I'm going to crash into a car that's already passed (Mitigated by accelerating slower and waiting for bigger gaps) and steering back me into parked cars because it's trying to stop me drifting over the centre line, I found a new thing!

While slaloming between parked cars and traffic islands, I must have been going faster than it liked or taken it at a shallower angle so it could still see the parked car - The Brake! warning flashed up, but this time it tried to steer me into the island and, for extra fun, put on the RHS brakes! Presumably to try and avoid the parked car that I wasn't going to hit anyway. Maybe they can't see the rectangular plastic bollard on the island?

This was only for a fraction of a second as I was quickly past both parked car and island, but I gotta say... these safety systems need work!

Is this the precollison safety system? Can this be turn off? Driving in a busy city, it can be a pain if it does this regularly. 

[Cyker]

It is, and you can turn them off; The problem is I don't want to as they have saved me from actually crashing into things a few times (Mostly due to user error admittedly!).

I think it's specifically a city problem, as nobody else seems to be getting this as much as I do.

I think the system is tuned perfectly for towns and more rural roads, but in London the streets are too narrow and there's just much less space for everything. It almost needs a 'city' mode that lets it trust the driver more, or maybe some AI learning so it can get used to the tighter tolerances.

That said, with more roads being blocked off with planters and the rest becoming 20 zones, the problem may soon become moot anyway! (Due to the whole city becoming one big 24/7 traffic jam...)

if you turn on the right turning signal light when passing the central line, maybe the system will know you will pass a line at right and not steering you back left.

Can any or all of these "safety systems " be turned off? if not I guess my new car will have a lots of fuses removed including the horrible noise that make when driving slow.

That's when the problems arise, some people can't make the correct decisions on the road lol

Lane assist can be turned off ( button on steering wheel )and the setting is kept. I turn it on only on highways, does not make sense to have it on on country road since it is engaged even when crossing the center line.

precollison safety system can be turned off (dashboard menu ) but it will turn itself on after another start. Via obd you can change the default sensitivity. In my experience - I got some false "break warnings" ( car parked in curve ) but the brakes were never engaged ) I thing Toyota's default setting is well balanced, not annoying at all.

That is good to know. 

Thank you 👍

[Cyker]

Yup, almost all the systems can be disabled, although each one leaves its own warning light on the dash to say it's been disabled and you also get a message on the MID, which would also annoy me!  

I just don't want to turn it off as, despite the false positives massively outweighing the true positives, there have been true positives that have saved me from an actual collision!

It will not be long before claims forms have "The car did it" tick box, as i have thought for years cars have become very over assisted

[Cyker]

I *wish* that was a thing, but this is why I'm not a big fan of automated systems or systems that take control away from the driver - The buck stops with us so even if the car did it and we had no control to prevent it, we get the blame.

It'll be interesting to see how they get around that if autonomous cars become a thing - Who becomes responsible? The people in the car would just be passengers, so would it fall to the car? Can you put a car in prison for manslaughter? Or would it fall to the company? Would they blame the person who programmed the logic? Or would nobody get the blame and autonomous murder cars just become legal?? We live in interesting times as the saying goes  

A mate also brought up an interesting point - How could it be legal for autonomous cars to drive on public roads given they don't have driving licences, or the ability to even pass a driving test?

Naw you won’t have to do anything Tony, Cyker’s car is trying to tell him something about his driving habits 😂🤣
