Using 1/9 rules. The phone divide into 9 sections. At 3rd box to 5th box, a calculation of speed been added. Example like less than 1 sec is over 60km/hr while 2 secs is 50km/hr or less. So, at box 7, the photo is captured. With data of the speed, it be send to lta.
I comes out with this idea as I saw at a coming fast at me while at my estate. Obviously, he is not travelling at safety speed n what if a child runs across the road? I also notice my area also having a lot of cars speeding n beats red light too. Accident waiting to be happen.
