My first car (petrol), in the 80s, did about 30 miles per gallon. I now have a Toyota Hybrid that can do 1 mile on battery. With this car, I can do just over 60 miles per gallon of petrol. The best I have achieved is 64 miles per gallon. This is a massive improvement. If we could further improve the efficiency of petrol based hybrid cars by around 40% then we could achieve our CO2 targets. The alternative would be to replace petrol with hydrogen but keep hybrid cars.

When I was working it did around 6,000 miles per year. I generally keep a car for 10 years from new as that is when, in my experience, problems start. This is 60, 000 miles in total. Now I am retired, I try to walk most places and only use the car for further away places. This means I use the car around once per month and cover around 2,000 miles per year. I fill up with petrol 3 or 4 times per year.

When driving, I try and avoid accelerating up hills while achieving the road speed going down hill. If I am at speed, then I use the down hill to rechange the battery by coasting. For example, on motorways I try and overtake lorries going down hill. At junctions, I try and start breaking quite early so that, again, the battery charges up.

I watched the Schrodinger's Car video. That seemed to be based on a large amount of research, i.e. science.
