Well same thing goes for many case's in automotive Industry: wheel alignment and balancing guys, Ac gas (freon) fill up guys, engine oil servicing guys doing 30+ points checkup.
If and whenever possible, stand on the head and get the job done right in first time.
This is really good news and first time I am seeing a clarity in this long standing grey area to use or not to use dashcam here.
TBH, I think cops here should allow and encourage everyone to use it and freely send the video to Dubai Police for below type of offenders:
Cutting 4 lanes horizontally at 120 w/o checking the shoulder
Driving in hard shoulders in busy traffic area
Swerve all of sudden ahead of you w/o any indication
Drive too slow in fastest lane and block traffic flow
Tailgate you and blink 100 times in a minute like an ambulance or fire dept.
