Hemet and the road

I had to go up the freeway to Hemet today and took the opportunity to learn more about the use of the cruise control. On the way up, I discovered for the first time in recent memory that people weren't passing me even though I was cruising at 61 mph. And on the way back, I saw the weirdest thing. The traffic in the second lane from the right suddenly slowed way down. It was a pickup truck travelling at 55, the driver all leaning back and taking it easy. After I passed him, I looked back in my rear view and saw three other vehicles pull in behind him and start drafting. Wow, this peak oil thing is making life quite a trip.
