I've just written to the HMRC, asking for a refund for some of my Road Tax; I was on a motorway yesterday, and the posted speed limit was 70mph, but due to the traffic congestion, I could only do 30mph. This is the third time this has happened this month, and I am not happy about it - I have checked the sign, and it definitely doesn't say "up to 70mph". I blame those big lorries and 4x4's towing caravans - taking up all the roadwidth, slowing everyone else down.
And another thing - last week I caught the GNER 225 High Speed Train to London - it only travelled at an average of 160kph, even though it says in big letters on the train "225"; It doesn't say "up to 225kph"! Would they give me a refund? Would they b*gg*ry!
