Sir the speed limiter is only for family cars and mild sports car.
Accord SIR easily brakes the 180km/hr barrier so is the Lancer EVO, Subaru Impreza and Galant VR4 not to talk about the Skyline GTR.
Even in Germany you can lift the 155mph barrier in AUDI, BMW and Mercedes etc on customer's request and own risk, they however do a high speed test before removing the rev limit.
Personally I think we should have a limiter at 155km/hr for C segment cars (Corolla/Civic) and 100km/hr for A/B segment cars (Alto/Cultus).
