Speed

Curious does having 16inch alloys make the speedo in accurate?

I got flashed on the way to the gym doing dead on on 30

It'll depend upon the section of tyres fitted too, significant changes to 'rolling radius/diameter' are what causes speedo. inaccuracy.

There was a car at the side of me that was closer to the camera, I 100% wasn't speeding, was watching my speedo becasue the road was straight and abit of a dip at the end, hopefully it was him, do they flash to warn??

No, but it'd depend upon actual speed, whether it's network or film-based, and if the latter, whether or not there was unused film still available at the time. Just forget about it unless/until you get a nasty surprise in the post

I had my sat nav on my phone while driving and when I reach 30 on the speedo on the sat nag it says I'm doing 27-28 so fingers crossed, thanx guys
