So Saturday morning, it's granny to the rescue! ('cept she doesn't drive), so can I drop her at Hemel Hemstead?

This evening, the wife goes down with the same bug, so can I pick her up?
Anyway, just back from a further attempt to wear my own set of ruts in the M1 and I can't help but marvel at how good these cars are.
155 miles this evening at an average of 61 MPH / 46.4 mpg, (despite the whole of Led Zep's Mothership on the way down).
