This morning Brooks and I went riding in the East Bay before work. Part of this ride is the descent of Calaveras into Milpitas. This is a fast fun descent.
Here's my strava gps log for the descent. On the right side you will see my average speed on the descent was 33.8 MPH over a 2.3 mile segment - over that segment size the GPS errors start to get pretty small.
About 1/2 mile from the bottom, the spidey senses went off and I did a shoulder check, and saw a vehicle behind me. I looked down and my GPS was reporting 34 MPH. There is one last S bend in front of me, and I drifted into the center of the lane to block the car from passing me. I didn't want to get passed in the S-bend at speed. This could hardly be contstrued as "impeding traffic" - the speed limit is 35 MPH.
Not surprisingly - I was passed right in the S-bend anyway. Shortly after the S-bend there was a speed trap, one of those signs with the speed limit posted and an electronic sign that shows the radar detected speed of your vehicle. The vehicle hit the speed trap - 47 MPH. Not surprising, as when I made the turn onto Calaveras there was nobody behind me and I was averaging the speed limit - the only way I could get caught is by someone exceeding the speed limit.
I caught the car at the stop sign at the bottom, but decided to just go on my way today. But I got a good look at the driver - a soccer mom in a mini-van with 2 kids in the car.
