Nope. I was on track to be 10 minutes early to work this morning and got there 30 minutes late. Why? Because going straight on a bridge is too hard for some people to manage. It was worse than a 40 minute delay for way more people because they're too stupid to understand the traffic pattern
that they drive through every day. I spent a lot of time stopped (with the engine off), but also spent a ridiculous amount of time idling in 1st gear past the stopped cars in the other lane. There was room for them to move over, but even watching us go by they still believed that their lane was the one to be in! I only saw two cars change lanes in a couple miles.
But really, variable speed limits won't work because speed limits themselves are stupid and are completely disconnected from safety. We'd need to convince people that this time, on this road, it's different. Get off this road any they're all irrational, based on focus groups, horoscopes and weather data. But here, we swear, it's based on road design, weather and traffic conditions. Honest.
