That's always a great idea to take pictures when you are going 100 MPH, nothing like taking your eye's off the road and documenting illegal speeds ;-)
Was just thinking the logistics of snapping the picture and keeping your eyes on the road and the car in control at the same time.
I have two phones, if needed I could shoot a "how-to video", it's not that hard... or I could be a professional driver on a closed course...
Thanks and yes, it usually is a great day in SoCal... However, the pict was taken in SoCO where it is always a great day & there is no traffic
