Living in Silicon Valley for 50 years and the traffic has died down to the point of it looking like how it was in the late 70's. When my GPS says I arrive there in 17 min, and get there in 15 min due to lack of traffic, it's kinda nice. When going to work, it's no longer 2-3 hours in morning/evening traffic. Just 18 minutes now. The air does seem much clearer out here, but it's been raining so will have to see how it goes later in the year on how much it impacted air quality.
