I was cruising on hwy 99 last night coming back from white rock, doing an indicated 122, which was the flow of traffic. A newer stock civic with the big digital dadhboard pulled onto the highway from an on ramp, and I looked down and saw the big numbers on his dash and decided to ride beside him for a brief bit.
He matched my speed pretty much exactly and I noticed when my dash indicated 122, his was only reading 110.
I've done a sprocket change so I knew my speedo would be a bit of fans that it's more exaggerated the faster you go, but I didn't expect it would be 12km/h off at only 110.
Anyone know a good iPhone GPS-based app that I can use to get a better idea of my actual speeds? I know there's speedo healers and such, but is just like to figure out my speeds in relation to some of the standard speed limits.
