My speed 483568.3 km/h

This Dashboard screen captured of Navitel Navigator 2 shows how I drove my old Camry recently. Despite the average and max speed of 6 figures I always stay away from booked.
That was because the police didn't have time to record it.
At 483568.3 km/h, I'm just a flash of light to him.

BTW, the speed of sound is 344 m/s (1238 km/h or 770 mph),
and the speed of light is 1,079,252,848.8 km/h

So, I'm at Mach 390! WOW!!
