Well I just had to try this today on my way home from work.
Had to say I was impressed with the way it stops. Very controlled but also pretty quick to stop.
So tonight on my way into work I thought I would try an emergency stop using the foot brake.
From around 45mph I hit the brake pedal VERY HARD and mashed it into the floor carpet. Damn, She stopped so quick. Even had a little chirp from the tyres as it activated the ABS system. The flashing hazards are a nice touch.
The foot brake is definitely more brutal, exactly what you want in fact.
