That takes some visualising for me only having driven through the madness over the last 40 years or so.
Always lived in the sticks.
It was a different world Rich. In the early 60s I was at university in Oxford. I had a Triumph Spitfire ( max 90mph, 0to60 maybe 15 secs/) but driving it on empty A roads ( there were no motorways) I could do the journey from home in Bradford to Oxford averaging just on 60mph. Admittedly I was young and daft but the roads were empty, no scameras, plod was in a Morris Minor or similar so you could go for it in relative safety. I only spun it once.
I havent a hope in hell of achieving the same average on the journey in my Ferrari nowadays. I wouldnt even try.
