I'm not sure that "targeting" is really applicable here. I sat at the intersection and watched for anyone who ran the red light, opening a report with them to ask why shortly after. If they did not have a valid excuse, they were gave a warning. A warning does nothing more than let other staff members know you have broken the rule and prevent you from applying to staff positions for a month.
Running the red light at the intersection frequently causes issues. Inevitably, a player blows the light going 100+ MPH, crashing into someone else and tiering their car. This costs the other player thousands and negatively impacts their experience, all because you want to save a few seconds whilst driving somewhere.
Suggesting that people cant do anything fun on the server because they have to wait at a red light is ridiculous.
