60+ mpg is good for the commute! A few suggestions:
The camera would probably be more steady if it was mounted rigidly. My brother has had good results in his car by using a homemade wooden mount fitted to the metal posts of the passengers headrest.
I find that turning the engine off during neutral coast to a distant set of lights, especially down hill can bring up average mpg versus waiting til the car is stopped to switch off. Im happy with the effort needed for when the PAS is inactive and when the vacuum for the brake servo eventually runs out when EOC.
In small cars I've driven (Saxo 1.1 and Cinquecento Sporting 1.1) keeping the revs below 4000 and using extra load, instead of more revs, helps by avoiding the huge increase in BSFC as friction increases drastically with high revs.
The Ford and Vauxhall owner's manuals I have at the moment advise along these lines "use 3/4 or 2/3 of full throttle and 2/3 or 3/4 maximum engine speed reduces consumption upto 50% vs full throttle".
Ive seen similar advice in most manuals ive come across so I similar generic statement should be fairly applicable to George
Apologies if I've missed anything or if you know my points and I've wasted everyones time on the internet
