If you look where many government ministers and other politicians end up after leaving politics and the decisions and directions of all political parties, you soon see the pattern and why the major parties refuse to step into the future and create industry that will not only drive massive economic growth, but also develop highly valued export industries and all sustainable. The fossil fuel industry is fighting for it's future when it doesn't have one, so are desperate to drain every bit of gas, oil and other natural resources from the ground, irrelevant to what it holds for the future.
My bus gets 3.5klm per lt towing a big dual wheel ex furniture moving trailer, running on veggie oil. With the amount of braking you do and it has an exhaust brake, regen braking would certainly put quite a bit of energy into the batteries and trucks can carry much heavier battery loads compared to cars.
There are some community advantages with EV's, charge points will bring people into towns instead of being bypassed. There will also be the need for technicians capable of diagnosing and fixing any break downs and chargers. The EV conversion industry is place to get into for anyone who wants to make a dollar or two, or EV parts and commodities. I reckon Ev conversion and no frills affordable cars would be the best market, not many people can afford $40000-$100000 EV's.
With the rate of fuel prices and supplies problems growing, converting your vehicle may be getting much closer. I wonder how many banks will lend funds for having your car converted to EV, was told between $25000 and $60000 to convert my cruiser by a bloke that converted an EJ Holden wagon.
