You have unintentionally provoked a rant and prediction from me regarding this subject. I have been interested in alternative forms of energy and transportation since I was a child. I have tinkered around and built up electric and gasoline powered bicycles and added electric motors to four wheeled "Rhodes cars" etc... This has been a hobby.
I have also experimented with fairings and windshields for both upright and recumbent bicycles for additional speed and comfort. I purchased my first 3-D printer with the goal of designing parts to help keep the price of "velomobiles" down with the hope of eventually manufacturing and marketing them. All of my creations have been intriguing enough to others that I have been able to sell each of them and make a little money in the process.
Electric cars are typically ridiculously expensive and have limitations that prevent them from being most people's primary transportation device. Without massive government encouragement and subsidies they still are not a good solution for our society's transportation needs as compared to traditional vehicles.
At this point electric bicycles are becoming very popular. An unintended consequence of this has been a huge increase in "bicycling" injuries and fatalities in the last few years. This is partially because of a huge increase in distracted and impaired drivers, but also because adding an electric motor to a bicycle makes it possible for people with little experience to whiz around much faster than they normally would be capable of.
In my youth I was a nationally ranked champion bicycle racer. I rode approximately 10,000 miles a year and my skillset was developed from all of these miles on the road so that I was able to mix with traffic more safely than others without this level of experience. These days the roads are much more dangerous in most parts of the country and now we have lots of yahoos riding around at higher speeds paying little attention to traffic and traffic laws with predictable results.
I am not really sure where all of this is going. We are likely to see a large increase in affordable electric vehicles. I am not talking about "Teslas", or "F150 Lightings", or even fire prone Chevy Volts... The biggest increases are going to be in electric bicycles and scooters, and glorified electric golf carts and enclosed little electric clown cars. Most of them will be cheaply made Chinese devices with limited longevity and poor recyclability that will end up clogging landfills after a few years. We should also expect lots of traffic disruptions along with a rise in deaths and injuries due to poor compatibility with more traditional cars and trucks.
