I'm in London. I cycle to work and use the tube network and bus network whenever I can. I also have a private car which I use for trips where public transport or my bike is impractical. It's a 2016 model, I expect that it may need replacing in 5 years time. If I took the cartoon at face value, I might think it makes no difference from a climate chang perspective whether I choose petrol or electric - and this is clearly wrong.
