It's awful! I was staying in a hotel one mile from my job's main office in Silicon Valley, so I figured I'd get some exercise and walk to the hotel instead of getting an Uber. And holy crap it was almost impossible. The sidewalk kept disappearing, especially at major roads and freeways, there were no crosswalks, I had to cut through multiple parking lots. I've never seen a place more actively hostile to pedestrians.

Lol. California is huge and incredibly diverse. I live in San Diego. I can walk to 4 different grocery stores in less than half a mile. Additionally, I have a weekly farmers market down the street I can visit. Not to mention the Ethiopian market and Mexican market that are an additional couple blocks away. Wherever you were in California only represents that specific area, and not the state in total by any means. I'm sure the area you visited has plenty to be desired as far as walkabaility, but I'm sure it's an issue divided along rural vs urban lines, not a state by state thing. Please don't contribute to misinformation. Making a sweeping generalization about a huge and incredibly populous state only adds fuel to the misinformation fire.
