I used to live in the Bay Area and have not really spent much time there in the last 12 yrs except on business. I spend 10 days last week on a family vacation and brought my V1 since I heard they being using Radar and LIDAR a lot these days. When I use to live out there very few people got speeding tickets you got tickets for lane changing, tailgating, rolling stops, blocking cross walks and the such.
Well here are my observations after 10 days and 1300 miles on the rental car.
First, the majority of the drivers do in fact drive the speed limit or damn close to it. I saw very few people who I would say exceeded the limits by more then 5 or 10 over. Except for a group of motorcycles who were doing well over 100 when they passed me.
Next, and I wonder if this would be a great defense against LIDAR. Most all speed limits signs I saw said the speed was in enforced with radar or by aircraft, nowhere did I see a sign saying LIDAR was in use. The fact that most all the signs had this warning tells me the State must have been required to post what method was being used. So since nowhere did it say LIDAR was being used could this be a reason for dismissal.
BTY, I did not get a single LIDAR warning, which was kind of surprising since I get false readings all the time due to taillights and the such back east.
On the Radar subject, I did get lots of I/O Ka hits, but could only identify a couple sources. The best I could tell was the officer was on the other side of the highway or they had some great hiding places. Most all the Ka were full power, no warning ahead of time and and only on for a sec or two. Unlike in PA even if they were using I/O you get some advance warning since that usually hit a car some distance in front of you. The best I could tell was the CHIP were being very selective in their targeting. They must have being doing some sort of tracking history then I/O the person once they saw someone going faster than the crowd.
I did notice MR was in used mostly outside the Bay Area, ran into it couple of times on our way to Yosemite. I had a great save on highway 140, got a few blips of Ka and thought it seem funny as I was coming down the mountain at 60 on PSL of 45, so I hit the brakes and slowed it to just over 45 and around the curve comes a CHIP SUV with is Radar full on.
On the subject of PSL, this drove me nuts I can not tell you how many time the PSL went form 50, to 55 to 60 or 65 and as far as I can tell for no good reason. I was on stretches of road where the speed was 60 then drop to 55 then to 50 and as far as I could tell the road conditions did not change. Also CA does not follow the MUTCD where PSL must be every 1/2 mile, I would drive miles and have no idea what the speed limit was since I had not seen any signs so I was paranoid I would have been over the limit.
Here is another interesting thing I ran across on 2 lane number highways, some of them had a PSL of 65 which is nice speed limit for a 2 lane road, however this same road had PSL of 55 for trucks. So here I am driving along at 65 and come up behind a truck doing 55. Okay some of these roads had passing lanes, which again is nice, but does not work well at those speeds when they are short and it very hard to see around a truck and you have to gun it to 90 to pass them.
This whole PSL thing in my mind is set up to catch you speeding, why else have PSL going up and down and have truck speeds and car speeds different on two lane roads and not post signs every 1/2 mile
Oh, the best one was the 70MPH PSL on section of road near Tracy which was right where a number of interchanges come together, why have 70 on this section and then 55 on a long stretch of flat road.
I also got to experience all your redlight cams. I saw signs all over the place that the intersection was protected by cameras. They even had signs posted at intersection that it was completely obvious no cameras were set up. At one intersection I was filling up with gas at night and watch the camera in action. I could see the flash going off like crazed even when no cars were in the intersection. It appeared it was just taking pictures just in case you were in the intersection. I did see it take a picture of a car even though the they entered on yellow and it turned red when they were in the intersection. I also saw it snap a picture of a car making a right turn on red. I see why you want to fight those tickets.
My buddy told me all the camera's were removed in his town since the town was sued over privacy issues and since this is local law, lawsuits have to be fought town by town. However, even though the cameras are gone the signs stayed, I guess they thought the signs were enough deterrent.
Maybe those who live there can comment on road mess that exist in CA these days. I see why you need to fight every ticket out there.
