The last two times on my daily ride I stopped at a major intersection with multiple stop lights in both directions. Both times as I looked down at my computer the mph indicator was jumping around, today it went to 100 mph and stayed there until I was moving again. Then when I got home it showed I had gone about 2 miles further than I usually do on that route.
I haven't noticed it doing this anywhere else yet. Am I a bit crazy or could the changing lights at the intersection be throwing off my computer. Anyone ever heard of such a thing?
