On my way home last night I forgot to start counting until I had gotten past the freeway, when I saw a backup as bad as I've ever seen in 4 years of bike-commuting. There was a stoplight out, blinking red, so I was passing 3 lanes of standstill traffic. I counted 100 cars and stopped; probably 150-170 in the end.

Then on my way in this morning I took a different route; longer, but also a lot of it on a MUP. I counted like 120, it was pretty early (like 6:30).

I'll try to remember on my way home tonight, to see what a normal evening rush hour is like.
