We're talking about a traffic light, James. You don't tell someone to go fuck themselves over a traffic light. It's clear that you need to go from semi-retired to fully-retired.
Why don't you explain to my incompetent intellect how this would work at a traffic-triggered intersection? Would the green hourglass be consistent, James? Or would the time interval have to change when people approach, rendering it useless?
You're talking to a programmer and graphic designer. But I'm sure your karate and sailing ability make you far superior at city planning.
