I had the driver's window rolled down ( which would destroy the local flow field ), trying to drive while holding on to the racquet.
If you could secure the racquet to something like the dual suction-cup holder, with safety lanyard, that CAR and DRIVER and other magazine road warriors use, attached to the door, downstream of the mirror, there'd be no 'harm' in 'looking' at whatever you saw. Or let a Go-Pro record while you concentrate on the road.
Information is information.
