Of course, we discovered that repeated hammering on the Nissan's brake pedal deformed something in the linkage in a way that makes at least one sensor think the brake pedal is constantly on. When this happens, the throttle will default to only 20 percent input (a similar strategy to prevent unintended acceleration is featured by cars from the German manufacturers, among others). The quick fix is to simply lift the brake pedal with the toe of your left foot, and then later we taped a couple pennies between the sensor and the perch it was looking for. Apparently Nissan discovered this issue shortly after this preproduction car was built and a permanent fix has been made.
