Joystick drift causes the controllers to read nonzero values when they are not being actively driven. To reduce the effect of this on the drive system, a deadband was added to the teleop logic to ignore low controller values since they are likely to be drift. This effectively makes the slowest possible input speed (deadband)*(lowest_speed_setting), but the default values make this minimum 0.025=2.5%, which is too low to drive the motors anyways.
