We may already be closer than you think. Analysts at Bloomberg New Energy Finance have predicted that more than half of new cars sold will be electric.
"We see a real possibility that worldwide sales of conventional passenger cars have already peaked," said Colin McKerracher, head of advanced transport for BNEF.
But in order for electric cars to really go against fog against gasoline-powered cars, a few things must happen first – and they won't happen anywhere at once.
Going the distance
First, electric cars have to move on a single charge and they have to charge faster.
Seth Goldstein, an electric vehicle researcher at Morningstar, foresees that, within 1
Since even 200 miles already far exceeds the amount most people drive in one day, the difference is mostly psychological. People are just accustomed to getting far more than 200 miles out of a gas tank.
Longer range cars come, thanks to improvements in several areas. Better batteries can store more energy. Meanwhile, improvements in production are driving down battery prices, which allows automakers to install multiple battery cells without running up prices too much.
Today, electric car batteries cost about $ 176 per kilowatt hour, but the figure falls to just $ 87 per kWh by 2025, according to analysts from Bloomberg New Energy Finance. (The kilowatt hour or kWh is a measure of how much energy a battery can store. For example, the Chevrolet Bolt EV has a 60 kWh battery pack, while the much larger Tesla Model S may have a 100 kW package.)  Electric cars also goes further thanks to improvements in the car's energy efficiency. More efficient electric motors and even more efficient tire assistance. For example, the new Tesla Model S Long Range builds on efficiency improvements in electric motors, tires, and wheels that help reduce rolling and wind resistance, with no extra battery capacity, to go 370 miles on a charge.
Car dealers will also have to think differently about "fueling" their car. When buying a gasoline-powered car, nobody ever asks, "Where do I fill the tank?" Gas stations are pretty much everywhere and it only takes a few minutes to fill up. With electric cars it is different. Charging the battery is not something people usually go over to do as a task in themselves.
Although electric car manufacturers are able to shorten the time it takes to charge a battery, it won't usually be a quick stop. Ideally, chargers will be placed where the car can be parked for a long time, such as in the garage, in the office or in shopping centers or motels.
But people won't buy electric cars unless they feel they can do an occasional long-haul trip without worry. This is where motorway riders come to rest. At present, there are several companies and industry groups that are working to build up networks of fast chargers.
"It is important to put these motorcycle riders in place at appropriate distances so that it is not superstructed," said Pasquale Romano, CEO of ChargePoint, which operates a network of electric car chargers across the United States . "And you have to build it a little ahead of consumer demand because they optically have to see it so they can get over the hump mentally."
Electrify America, a charging network company funded by Volkswagen as part of its diesel emissions scandal, is also rapidly building a charging network and having agreements that allow the network to seamlessly collaborate with others. Tesla itself also has a large network of Superchargers worldwide that the company often points to as an important selling point for its cars and SUVs.
And the chargers are getting faster. Swiss industrial companies, ABB, claim that chargers will be able to fill the car's battery pack to 80% in under 10 minutes. This also depends on cars being able to accept a charge this quickly, though. Cars, though, will vary in how fast they can charge. Charging currents are already a bragging point for car manufacturers.
More choices, better prices
Beyond that, one only needs to be several electric vehicles for consumers to choose from.
In the automotive industry, there is always a difficult interaction between what customers want and what is available. For example, crossover SUVs are very popular with car dealers these days. It is partly because there are so many crossover models out there . It wasn't true a few years ago. The result is a huge increase in crossover sales – both because customers want them and because the dealership is carpeted with them.
Currently, someone who wants to buy an electric car will have few opportunities. But as more competitors enter the market, sales of electric cars will naturally increase as customers are more likely to find an electric car that fits their basic needs and tastes.
Until recently, electric cars have not kept their resale value as well as gasoline-powered cars.
It's starting to change, says Eric Ibara, a resale value analyst with the Kelley Blue Book. The key factor seems to be range. Electric vehicles with a longer driving distance keep the value better, he said. The Chevrolet Bolt EV, for example, has its value as well as comparable gas powered Chevrolet cars.
The challenge will make customers see it. Corporate fleet buyers understand it easily, he said, because they tend to look at their cars and trucks as business investments.
"Private customers, usually look at the price day for purchases, and then they forget the rest," said Stackmann.
The timing is approaching fast, Goldstein says, when electric cars will be just as good a choice for consumers, even without any additional purchases.
"If you take charge infrastructure away and you take away incentives, just look at when [electric vehicles] will be as good as a [internal combustion-powered car] it will happen in 10 years," he said.  And when that happens, electric cars will cease to be such a novelty and begin to really take over.
