I moved back to SF in June after a year away, and noticed cars going faster on 101. Now, I'm regularly going 75. Did anybody notice this trend? Or was it my switch from Accord to Wrx in the meantime?

 

from what i know its 65-70.....more likely its 65....unless there indication of some other speed......as for people going faster....its cali.....people usually do 80...for dayam sure i do..and its even worse down in socal....like on 5, or 405...and yea...its probably your switch from accord to wrx haha....

 

did you have bigger/smaller tires than oem? that could throw off your speedo.

of course if you have an STi, your speedo is -4mph over 50 mph to begin with...

 

which part of 101? after 280 split or before? if after it's 55. before is 50. there aren't much chp on that part. i use to do 80+ back than before i got a speeding ticket :\ (in another area)

 

If you dont get caught there is no speed limit.

 

I see the signs that say 101, I figure that's fast enough for public roads, so I rarely speed on that one.

 

Hehe...

 

design speeds for all roads are 5-10mph over the posted speed limit in ca. usually

 

isn't it the speed posted it only 80% of the actual speed that it's rated to be safe at?

 

when i went to traffic school recently, the guy said that the max. speed limit on any road in california is 65mph unless otherwise posted.... so id think 65.

 

there is an engineering survay in the local traffic court that has the actual 'safe' speed limit. If you get a ticket that is above the posted speed limited but lower than the engineering survay, you are okay. OR, if the survay is more than 10 years old or something, you can get off the ticket simply by presenting the survay, which is available for public access.

 

The design speed depends on the traffic index, from what i've seen most city roads are like 7.5mph over the posted, and freeways and expressways are like 10mph. Of course the traffic changes and a lot of them aren't up to date as posted above.

 

In my estimation the speed limit on 101 varies from 55-80, depending on the asshat factor. I've been stuck on that damn road behind a wall of four cars doing 55 for miles.

 

There are places on the rural parts where Porsche Boxsters meet their speed limiter as the Forester speeds past...

 

101 is 65 except for the part by vermont exit and the split to civic center/4th, etc... there it's 50/55....
