I was at the left turning lane coming from Foothill RD (Stoneridge). Who knew I was going to get stuck in Foothill High School traffic ?? My light turned green for W Las Positas RD however driver's from behind me decided to make a left turn too by purposefully creating an invisible 2nd turning lane, blocking traffic by packing in like sardines. I have seen similar traffic congestion at Hart Middle School. This white female in her mid 50's absolutely had NO patience to wait for another green light. Where are the police when you need them?
