Those heavy BLACK arrows ( left, right, or straight ahead) encircled with RED and a diagonal running through that hang on traffic light arms aren't there as a joke. Yes, I know the (worst offender) T-intersection at Walmart on the carretera was designed by a lunatic high on drugs and booze who'd never visited their work before or after. Yes it's a MAJOR P I T A to all, me included. But those arrows are there for a reason.... and not just in that location.
Do I care when those to whom the rules "don't apply", or who are simply too lazy or important to obey them, break a law on ignoring? Only a little.
What I DO care about a LOT is your behaviour has a direct possibility of affecting MY life ( or someone else's) in the event your actions provoke an accident that could result in my/their car being crunched or I/others are personally injured........or worse. (Yes... I'm insured. Not all are the same.) Driving is a privilege... please don't abuse it.
