Battery-run vehicles for physically challenged people

The other day I saw a man pedalling a rickshaw with only one leg he had. After dropping off a passenger, he stopped near my house. I asked him why he was doing this. He broke down in tears and said he had no other way to feed his family.
I felt sorry for him, but at the same time, I admired him for doing such hard job instead of begging. It would be a lot easier for him and countless other disabled people to work, if battery-operated vehicles were legalised. I hope the government would think seriously about this and come up with a solution as soon as possible.
