Yes, It may not be 30% but could possibly be more.
In this current year, the entire world is in crisis as we are are struggling from the rising temperature and global warming. The transportation modes do play a major role in the CO2 emission and contributing to the global warming. While many countries are already looking for the clean source of energy, there are many who are joining the cause and I strongly believe that the world will come together to fight this. As for the Electric Cars, I think it is safe to assume that the manufacturer will be joined or made to change the idea around to fit the clean energy source.
Plus I want to see the future where the cars are completely automated and run on electricity. :-)
