The Prius tells you how much of each journey is spent using EV power alone (the remaining figure for the ICE use, as i dont EOC!).
You have to move through a few screens to see this, i rarely bother - but it proves fairly high, like 47% EV.
I supposed for me i could do with seeing how much of each journey would be;
1, ICE
2, EV
3, charging battery with engine off
I also have assisted acceleration, where battery and engine work together.
So i'd need 3 or 4 chess clocks - as i wont even put my old Scanguage E on my uncluttered dash, that wont be happening!
As long as it wouldn't dangerously interfere with your level of concentration, i guess it's worth a try.
I experimented by driving late at night on quiet roads - virtually no traffic meant i could dawdle along at 25 mph, maximising my EV use.
I guess its similar to submarines - they could travel 80 miles at 2 knots submerged, but less than a quarter of that at 8 knots. The slower i go, the more EV range i get from the battery.
I managed an indicated 95 mpg over 35 miles, while having to drive at the same speed as traffic during the day, 65 mpg indicated would be the best i could expect. The improvement came from the longer times my engine was off, either charging on downhills or using little battery power to pootle along for far longer sections than possible with a 4 x 4 or an Audi close behind.
Viz did a top tip once, something like; "Audi drivers, make sure your seat is as far forward as it will go to get even closer to the car in front"
