That's a huge development, Science and technology are improving day by day, new inventions are coming, the scientist is making things to give human's comfort. The electric car is one of them, yes you are right if we go 10 or 20 years back, no one has ever imagined that there will be electric cars, that will use decrease the use of petrol. we all know that burning petrol is a source of pollution for the atmosphere. this is a huge development. Do you know way back in 2012 A Pakistani engineer has built a machine that will run a car using water, The experiment was successful, he tests it live, That would be a revolution but our government is cheap has stopped him because they were getting huge benefit from the petrol, These cheap guys have hidden that man, and now no one knows where he is. Technology is growing too fast, and in the coming years, we will see a huge change. I am happy for you and your city that no you have Electric cars and now there will be less smoke and pollution.
