If you're taking the A1 don't get too excited, as south of Sheffield down to around Stevenage is fucking littered with speed cameras

It's clear past Leeds up to N'castle though, so give it plenty of welly

Strangest thing about driving a TDCi... you can be doing 90-100mph on the motorway in 6th gear, and it'll only be pushing 2500rpm ! My wife's Puma (Zetec 1.7SE) would be easily pushing 5000rpm at those speeds
