The idea is simple. We currently have success with some brands of electric cars. Namely Tesla. What I can’t understand is why not go after public transport. For one thing. The renew cycle is to long. Another is that the busses would require very large batteries. To solve this I think we should have electric minibusses. The most important reason is that the batteries could work for these sizes and weights.
So the idea is to use smaller busses with electric car battery technology. This might need more drivers but think of it another way. It will generate more jobs and zero emission is living space friendly.
