Yes, but as individuals we can all add momentum to a chain reaction. For example, if you use an e-cargo bike for the school run or a big supermarket shop or taking a friend to the pub, car drivers will notice. You will overtake some of them and get a better parking spot. Some will copy you. E-cargo bikes then multiply, and their mere presence builds the case for bike friendly infrastructure, secure parking and so on, so local and central government react. Consumption of petrol and diesel in your area declines. This strengthens the hand of your government when they go to a climate conference to persuade the likes of China and India to do more. This is one of dozens of ways the individual can influence societal change. If you refuse to do these things until China and India or your own government make the first move.....it's just barmy. And hostile to your fellow humans and their descendants.
