Bit long but a very good thought and analysis for the future mode of transportation. Am an engineer from INDIA and working in an automobile OEM.

Yes as from a person from advance planning department we are targeting to the market with autonomous vehicle in next 3-4 years. ...It definitely has the future, But when the news of accidents are coming from around the world it seems difficult to get the clearance from government in the near future.

Flying car would be very good to see, especially when traffic jam has troubled in every developed country.But for that air traffic system has to be developed first.

Thanking you for the post @saswat036
