The storage corridors were deserted.  Lemke sprinted for a row of parked electric cargo transporters.  He heard the cops enter the cooridor behind him.  They didn't bother with a warning before opening fire.  The gunfire reverberated in the empty corridor.  A bullet struck him in the back but flattened itself against his armored jacket.  Another nicked the top of his ear.  He clambered aboard the nearest of the electric vehicles and hit the activation stud.  The cops drew four abreast in the corridor, their guns leveled at Lemke.  He gunned the engine and headed straight for them, ducking down as the first fusillade of bullets sparked and ricocheted off the vehicle.  The cops fired relentlessly, but the bullets had little effect on the solid plastic tires and the distributed electric motors.  They stood their ground firing until the last second when they jumped for the walls.  Lemke anticipated their dodge and spun the wheel so that the vehicle's cargo trailer swung across the corridor.  Three  cops were too slow;  the trailer sent them flying.  Lemke turned the vehicle and scraped it along the wall, giving the cops who had avoided the trailer the choice of jumping back into the bar's kitchen or being crushed.  They dove back through the doorway.
