so I am on a 30 mph road
I am doing 30
tge speed checker thing also tells me I am doing 30... in red 
if I do 25 it is green
if I do 28 it is Amber
if I do 30 it is red.
why? why???? I'm doing the RIGHT THING
fuck off with your red 'warning'

AIBU?
disclaimer: I know this is not really the biggest problem in the world but I bloody hate it!
