Sometimes people realise during an overtaking maneouvre that they've misjudged it and need to put their foot down to get out of trouble.....with a speed limiter there may be no response from the engine at the critical moment.
I posted earlier:
“ISA systems do not automatically apply the brakes, but simply limit engine power preventing the vehicle from accelerating past the current speed limit unless overridden.”
To make the move more popular, the ETSC proposes an on/off switch to be included at first,
which would allow the system to be overridden by pushing hard on the accelerator.This override would allow motorists to speed up should circumstances need it, and could mean that stricter rules could be introduced in the future.
The ETSC also suggests that “if the driver continues to drive above the speed limit for several seconds, the system should sound a warning for a few seconds and display a visual warning until the vehicle is operating at or below the speed limit again.”
