I agree that cars are necessary in some countries and places. Why are you preaching to the converted?
That’s why I am suggesting things like Biodiesel because I know cars aren’t going away everywhere. I also know diesel trains aren’t going anywhere for at least a decade, hence why I also suggest biofuels here too.
If you want a new car that’s good for the environment, buy a second hand diesel then use it with biofuel. You can buy or make biodiesel yourself. Some engines can run straight vegetable oil too or can be converted to do so. This is handy because vegetable oil can be bought from any super market and many businesses throw away used oil that cane be reused for running a car.
What is protest about in your opinion then?
