They may not solve congestion, but they should lower it, even it it's by a tiny amount. The reason is simple - electric cars don't have to visit gas stations which sometimes adds few miles to the miles traveled every month. i.e on my way to work I have just one gas station. When I have to fuel my car, (usually once a week) I have to take a different route that's about 1/2 mile longer than my usual route. That's about 25 miles /year. If we multiply this by 260mln passenger cars on the roads we get 6.5 billion miles. Let's go little further with this.. if set avg fuel economy for all of these cars at 20 mpg we get 325000000 gallons of fuel saved each year when all of the cars are electric. Funny how small little thing can have big impact. Of course this is just a guesstimate.
