Anyone able to help. Think I might have been caught speeding. On the motorway this morning, think I got clocked by a police van on the bridge above. I was definitely not doing 80 but was constantly fluctuating 77/78/79. There is often 3mph between my Speedo and Google maps on my phone. No other speeding fines ever but really worried what might happen. Struggle with anxiety and worry about absolutely everything but I can't think straight and can't eat - please help, how much trouble am I likely to be in
