Only adjust the rear-view mirror
							                                
                                        
                                    
							                        
                    
                            Ignore the mirrors as visibility is low in tunnels
							                                
                                        
                                    
							                        
                    
                            Rely on cameras instead of mirrors
							                                
                                        
                                    
							                        
                    
                            Ensure they are clean and properly adjusted
