Endangering traffic and average speed are coupled together. Endangering traffic is when one drives at a higher or lower speed than the prevailing average speed on the road. So the lil ole lady in Phoenix driving her 1969 Chevy Impala at 25 mph when every one is driving at 55 mph is actually endangering traffic just as the macho guy doing 75 mph.
The notion, that most drivers have here, is we own the road.
One finds the guy that drives at 120 kph on the second lane down Shaikh Zayed Road when everybody else is averaging 140 kph and then wandering why everybody is passing him on either side and giving him the evil eye. But what is worse are those who think they are F1 drivers on a speed track doing far more than 140 kph, head lights flashing, riding your bumper while you are having nightmares of what will happen if you have to brake for any reason.
It makes me wonder if these people have any idea of the consequences of their actions. Having a driver's license is like having a permit for a big ass projectile.
Safe driving people and God Bless
