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.
