Grey manual for me.

I did indeed (even got a discount on the original price), and I'm not a fan of the whole ISA idea either (nor of the looks of the new car, both outside and inside) :D Maybe the mk2 still has to grow on me... but for now I'm going with the mk1

Does anyone know anything about the ISA system for this car? Is it actually on the car and how does it work?

In theory, according to article 6 of Regulation (EU) 2019/2144 of the European Parliament:

2. Intelligent speed assistance shall meet the following minimum requirements:

(a)it shall be possible for the driver to be made aware through the accelerator control, or through dedicated, appropriate and effective feedback, that the applicable speed limit is exceeded;
(b)it shall be possible to switch off the system; information about the speed limit may still be provided, and intelligent speed assistance shall be in normal operation mode upon each activation of the vehicle master control switch;
(c)the dedicated and appropriate feedback shall be based on speed limit information obtained through the observation of road signs and signals, based on infrastructure signals or electronic map data, or both, made available in-vehicle;
(d)it shall not affect the possibility, for the drivers, of exceeding the system’s prompted vehicle speed;
(e)its performance targets shall be set in order to avoid or minimise the error rate under real driving conditions.

According to Annex II of that same Regulation:

Date for refusal to grant EU type-approval: 6 July 2022
Date for the prohibition of the registration of vehicles, as well as the placing on the market and entry into service of components and separate technical units: 7 July 2024

From how I understand it, no EU type-approval can be carried out after 6 july 2022 without the car having ISA (as the car has a new front bumper, it will probably influence aerodynamics and probably the WLTP standards, meaning it requires a new EU type approval). Above that, every new vehicle registered after 7 july 2024 needs to have ISA (and as the mk2 will be delivered after that date, it will need to have ISA).

(PS: I have read somewhere before that the whole idea was that, eventually, ISA would prevent you from driving faster than the permitted speed - but it seems that it can still be turned off in this fase...)

Its interesting as those GSR2 regulations are yet to be adopted in the UK but we'll probably end up with it as the car will need EU type approval.

I'd like to know how the Toyota implementation works though, anyone have the latest Toyota Safety Sense on another car?
 
I expect ISA will be on the new model. Saw Harry’s garage review of the defender 130 this week and it had it on (he promptly turned it off as 99% of drivers will).

Mk2 has a custom drive mode, remains to be seen what exactly can be programmed on it...

This is also one of my main questions/concerns regarding the updated GRY.
Hopefully Toyota thought about this and let's us disable ISA with a one button push.

It's likely a button on the steering wheel, maybe one of these:

If this is true, im not interested in a new Car.

"
New vehicles in the EU must from the 7th July 2024 to be equipped with ISA. The assistant points out motorists to exceed the speed limit by acoustic or optical signals.

The assistant can also perform an automatic slight throttle removal, in which the accelerator pedal pushes slightly upwards against the foot or vibrates, in appropriate driving situations, explains the Auto Club Europa in a press release. !"

!!CANNOT be switched off!!

Ok, i buy a new daily before and im out for the complete Car market :(.

you need to order JPN variants via Sweden. I think new RC would be sweet. if it lacks ISA - of course. ISA reminds of International Space Agency - maybe these rules are planned in space.

Instead of speeding, cars should follow the driver that person doesn't use cell phone or laptop while driving. Doing something else is much more dangerous than actual speeding. ugh, I've spoken. The strange approach in this legistlation seems to be quite common.

I just read the article on ISA, it looks like despite leaving the EU some time ago the UK will be forced to adopt the regulation by pressure from the car manufacturers themselves. They don’t want to build different versions of Euro market cars just for the UK so the cars will come with all the same software and hardware as EU market cars.

ISA employs visual, audio and haptic feedback before cutting engine power to reduce speed. Can you imagine how hideous this will be in practice? I just can’t see how or why anyone would want a performance car with this technology, it would completely destroy the enjoyment of driving for me.

I don’t drive around speeding everywhere, I often find myself driving through a village and an SUV will appear at a great rate of knots in my rear view mirror. My concern is that I trust my own judgement as to what is an appropriate speed for the road and conditions, this is often below the speed limit and sometimes over it.

Having the pedal vibrating under my foot, whilst the dashboard lights up and alarms are pinging in my ear is not my idea of an enjoyable driving experience.

I really like the new GR and I’m pleased that Toyota are continuing its development with all the pressure to force us all into characterless milkfloats. But if I was wanting to ‘upgrade’ now (I’m not), this would be a huge barrier for me.

That's the problem with all this EU nonsense. Nobody decides for themselves anymore. The EU takes care of your security and takes YOUR decisions for you.

Does anyone actually know what it'll be like in the new GR Yaris. It's part of Toyota Safety Sense 3.0 so I'm guessing other vehicles in the Toyota range will already have it?

It might even be a feature that can be disable permanently , our 2021 RAV4 has lane assist and unlike the current GR Yaris it remains off between engine restarts and you have to manually turn it back on. The ISA system may well be like that on the new GRY. The technology is being phased in so I very much doubt it'll have haptic feedback it's probably some kind of visual/audio warning.

The EU is getting scarier and scarier every year, and more and more totalitarian, not just around cars, but about many things. So many scary suggestions up for consideration in the EU these days, getting more and more power in terms of deciding the national budgets of member states.

I'm not sure how effective a democratic system can be when you move the people in power further and further away from the voters with more and more layers in between.

I know it was popular to laugh about Brexit, but in hindsight I think the UK made a smart decision in the long term.
