I think the general consensus is right, you ar probably used to having to floor the pedal in a slower car to get it to move - not needed in the ST.
However, I have on occasion inadvertnetly caused wheelspin, once quite recently was coming back from a friends and was trying to get home quickly and gave it too much joining a round about, was stuck on the spot and there were several pedestrians which must of though "what an idiot"
Ah well, it happens, but you will get used to it given a few weeks
