Seriously, how long can one last at 200+ kph, in an SIR? 5 minutes? 10 minutes? Or a few seconds, just long enough to claim bragging rights? At that speed, inside that car?

Its borderline suicide! Remember what the W140 S280 of Lady Di looked like after it crashed at high speed? That was a car way much bigger than an SIR.
