In my test drive on Saturday I was interested in the creep/no-creep issue. On a slight uphill slope and no foot on either pedal, I let the Model S come to a stop, and then it started to roll backwards. In a manual car I'm used to using the handbrake to stop this, but the Model S has no handbrake. I used a slight pressure on the accelerator to balance it and mostly stop the roll. In such a short test drive I didn't get a chance to experiment more, to see if perhaps a brief press on the brake pedal would cause the Model S electronics to lock the wheels and prevent the roll. Anyone else have any observations to report on this?
