If you want better vehicles go drive a Tesla S P100D - a 4 door sedan that will blow your mind in 0-60 and is basically quicker then everything else. Clean coal does not exist and probably never will. There is no financial incentive to invest in such technology. Natural gas is the primary cause, however, solar and wind power will seal its fate. Man is a primary cause of the current climate change crisis - virtually all of scientist agree. And if they are all wrong it still means a lot of good things. Cleaner air, water and land, energy independence and not sending billions to the Middle East to fund terrorists. If you are wrong the consequence will be catastrophic. As to a financial burden - it is the exact opposite. Solar and renewable energy is one of the fastest growing industries. I put solar panels on my house. The payback is @ 6 years and I am producing @90% of my electric use. I will be adding more to feed my future electric car - probably a hybrid to begin with. Hoping Lincoln is going to come out with the Aviator that they have designed to challenge the Volvo XC90 T8. Even Range Rover is coming up with a hybrid version to get 30 miles all electric range. Sorry to disappoint but the train has already left, electric cars are the future - and they will be here before you know it. If Lincoln is to compete they need to move forward to the future - not try to remake the past.
