OK last night was a normal commute home, I counted 357, that's probably +/- 15.

I forgot to count on the first little section, that was maybe 5-10 cars, it's only like 100 yards.

Then turn left on the big artery (3 lanes each way) that leads to/past the interstate, I counted 160 in about half a mile til the freeway, and made it to about 300 while still on that road after the freeway. Turning onto the other major road, I got up to 356, and for the last mile and a half I take residential streets, only one more car passed me.
