I was unfortunate enough to have to be out in rush hour traffic this morning - went to one place before the traffic built up, coming back, I was against the traffic stacking into town, Hedon Road, Castle Street A63 all past the marina grinning my head off at people in their cars stony-faced...and stationary. :tongue:


good to read about another hull rider don't see many about on my travels
Good job I didn't ride into a lamp post!

Bike computers are pretty accurate if you put in correct wheel size. Cars are out by about 2-3 mph at 30. Most over estimate speed.

Hehe, I love racing cars. If you can find a road where your average speed matches theirs, some of those cagers get soooo wound up.


I checked my cars speedo with the GPS and it definitely under reads. However, I discovered the average-speed readout on the trip computer is accurate - you end up going 2mph faster than everybody else through the average speed camera sections if you use it without breakin' the law.

Yep, N1 Fossy :smile:

Kept up with a colleague today between a few lights at around 20-30mph. When he finally leaned out of his window to tell me to "bugger off" I just had to filter ahead and sit right in front of him. :tongue:

Shame I messed up with the clips starting off and made myself look a little silly. :blush: :laugh:
 
What makes you think your speedo is more accurate than the car btw, especially as they are legally required to be within a certain tolerance and yours isn't?

The requirements on speedo accuracy is -0/+10% so that it can never under-read leading to you breaking speed limits while doing the indicated speed limit. Most manufacturers calibrate at the +10% end so when the speedo shows 30mph you are doing 27mph. Mercedes are the only cars I've calibrated with GPS that come out spot on for speeds. All the rest over-read by close to 10%.

To get your bike speedo wrong by 10% you would have to mismeasure the roll out distance of typically 2m by 20cm or 8 inches. I would guess most of us get it within 1cm which would give an error of 0.5%. So the bike computer is likely to be far more accurate than the car speedo.
 
By a colleague........... :ohmy:

Doing 28 mph on the A34 - speed limit's 30 :biggrin: on my fixed into a headwind.

Shame the car speedo is out slightly as my computer was reading a smidge over 25 mph ! I didn't tell him that ! :tongue:

The colleague happens to be a cyclist, but he was in his car !

25.8mph was the average speed of the 2003 Tour de France (the highest average speed Tour) just to put it in perspective ;)

Ah this is more like it. When colleagues think you are the poor relation in the office, but out on the road they start to realise a bike is better, especially in traffic. I've raced colleagues between sites before and the look of 'wtf' on their faces when you glide past them just at the end of the route.

I think my Wife has finally now realised that I don't "do pootling".

Her Dad went to her workplace to get a lift home with her to Babysit for us that night and they were just waiting to pull out of the front exit of her workplace when I went past on the main road. My Wife said "Oh, there's Hubbie heading home" to which her Dad said "Well, we'll catch him up soon I bet" and she replied "No chance. We won't see him again until we get back to the house" (about 3.5 miles away).

She was right. :thumbsup:


Good speed, Foss. No point hanging around, eh?!? :biggrin:
