Per my Garmin GPS. So you can go 2 mph faster then you thought and not get a ticket.

 

*edit* got a clue, said the same thing :D

 

The 2mph seems to be true on my RX-8 as well, according to those speed reading / display things put up by the cops.

They do that here sometimes in California to remind you how bad you are.. usually the device is next to a speed limit sign :D

What I meant to say... it seems to be 2 mph across the range from 30 to 80 mph.

Haven't run into those devices while I was going 100+

 

I just hit one of those radar things also and I was exactly 2 mph over at 75 mph.

 

that has also been the case with my old 93 corolla and my 99 camry and my moms 00 sienna. maybe its something car makers do on purpose?

i love when they put up those speed reader/displayers up. there are never cops around them so i always floor it to see how high i can get it over the limit. my record is 68 in a 35 (dont worry there werent any cars/people around).

 

I cannot rely on that :-(

on my commute home there's such a sign now in a downhill curve (on highway 17 for those in the Bay Area)

it's actually a permanent speed reader integrated in a street condition display thing, and half the time a cop's around the corner, having just pulled someone over.

As someone stated here before (quoting a cop who had just given him a ticket)

"California is out of money and I (the cop) have been instructed to squeeze fines as high as possible out of you"

:-( really takes the fun out of owning a nice car.

 

So its reallya fact that our speedometers show 2 mph more than what theyre actually going? So wedont actually reach 60mph until our speedometers read 62?

 

yeah, ive noticed the same for mine at least at speeds from 15-50. it actually seems to be something more like 1.8ish, b/c sometimes i can get the radar to read only a mph higher before my speed drops one mph

 

exactly jerky. and this is not the first tiem this has been discussed

read here

and here

and this link to 4 more threads that i have mentioned it in.

this one about odometer inaccuracy

 

Wow sothen I guess for the Rx8 from now on weshould all refer to our 60 times as going rom 0 - 62 in -.- seconds. Im going tostart driving 2mph over what I usuallydrive now whenever I go under 60 and if geta ticket Im blaming it on you guys!!

Bythe way to addsome more wonderful news to this post all of this meansmy automatic Rx8 is slower than I had thought it was. All thattime I spent having my 0-60 timed was actually how fast it got to 58 mph. Im disappointed.

 

Yeah, 2 mph over the speed shown by the GPS (Garmin StreetPilot III) here as well.

 

Your times, maybe - it's worth noting that the car magazines never use the car speedometer to time acceleration runs. They always use precise testing equipment that gives them a true speed readout, so the 0-60 times you read in the magazines are not using the (less accurate in all cases) car speedometer.
