No, they are not. Cars must alert the driver if they are exceeding the speed limit, but there is no forced limiting.

Many expect the EU to eventually remove override capabilities as the systems become more widespread.

Basically impossible to get through. As there are often cases where it picks up a speed limit from something like the off ramp on the equivalent of a highway. Which would be dangerous if it suddenly decelerated from 130 to 80.

Speed limiters aren’t connected to the brakes, just the throttle.

Well, at least mine is actually connected to the brakes.

"ISA [Intelligent Speed Assist] systems do not automatically apply the brakes, but simply limit engine power preventing the vehicle from accelerating past the current speed limit unless overridden."

See https://etsc.eu/intelligent-speed-assistance-isa/ for list of vehicles.

No, it actually applies the brakes automatically. The ACC as toyota calls it.

ACC is their collision avoidance system, which isn't part of the EU mandate.
