The point is the electric cars of 100 years past are competitive today. If you put LiPos in a 1910 electric car, you can go 100 miles, drive it around town, etc. You can put a fuel cell in it and drive it between major cities (but bring goggles).
Batteries have evolved. Electric and methanol/hydrogen fuel-cell car is coming for all of us.

I forgot if I mentioned yet, but if energy gets to be rare/expensive, we are going to have a society breakdown nice Mad Max style, so for those times, gasoline cars are more useful. Imagine Mad Max hooking up to a generator his electric car.

I'm trying to say that electric cars, boats, trains have always been all around us. Now that we can package a few kilowatt-hours (undreamed of in 1910) into a small car, things are going to change.
Now that we can collect power with these if we have sunshine, these if rain and make it into portable energy with and upgraded one of these and charge these. It's all here.

This is a good article about battery cost. The business tipping point is said to be $350 per kWh and we are currently around $1000. They think we will reach it in 5-10 years.
Let's repeat it, 5-10 years.
Now as long as the hybrids are more viable than EVs, automakers don't have the incentive to put too much energy and money into R&D...

How about this, we have more electric cars today then any other time in history and the rate of electric car market growth today is very rapidly. Might as well as told us in 2000 that hybrid cars would never take off.

I just mowed my lawn with a battery-powered mower, as I've been doing for a couple of years. It's already easier and more pleasant to move beyond the petroleum daze.

But for a challenge I raise your city commuting electric golfcart device with:
This is hardly a car, just a dirt cheap commuting device for the masses, but:
1. Its price is only 10% of today's EVs. It is less than $3000. It is so cheap, that one can buy a new one in every 3-4 years, thus changing major components is a non-issue...
2. Its range is 2-3 times bigger, 240 miles on highway...(61 mpg on highway, 52 in city with a 4 gallon tank)
Sure, they gave up lots of safety and comfort, but we are talking about a solution for the masses. Maybe that is the way, giving up certain features. Somebody earlier suggested speed limit for city driving as a way of helping EVs. Well, why can't we help the Nano the same way??? Rush hour traffic is seldom bigger than 30 MPH anyway....

I think this thread has reached its 'use by' date. Syzygys is no longer insisting that evs will never be practical - just that it is a decade or three till they become as common or more common than fossil fuel propelled cars. This, to me, is a realistic approach.
I think we have demonstrated that electric cars are not a pipe dream, and syzygys has demonstrated that it will not happen, except on a small scale for some years to come.
Can we all agree on that?

Let's say the commuter drives 25-25 miles a day, car is useful for 5 years, after that you will need to spend major expenses like a new battery and such.
So 50 miles a day for 5 times 250 times. 62500 miles That costs 62500/50=1250 gallon x 9$ = 11250$ for gas. Let's throw in 1000$ for oilchanges and the price of car of $3000.
That is 15250$ which is exactly HALF of the current EVs' prices...
So you tell me a low cost, low mileage gasoline car is not competitive with current EVs.
I understand your frustration, it is basicly impossible to compete a cheap Indian or Chinese made small, economic car. I would bet Americans also could make a cheapo 8K car, but there is not much profit in doing so...

Mind you right now NOBODY is making them in huge quantities. I am sorry, but making 30K cars a year is not huge by any measure.
Oh yeah, just to piss off EF and throw in a little history, there were 32K electric cars 100 years ago. I seriously doubt we have 320K nowadays. If we adjust for population, there were actually MORE EVs 100 years ago then now!
Oh, analysts predict between 2-10% EV marketshare in 2020, fairly far away from 51%:

It is the Chevrolet Aveo
MSRP: $10,235 - $12,020
Fuel Economy: 34 mpg Hwy/24 mpg City
So running the above math again, it uses 2500 gallons in 5 years, what costs 22500 $ ($9 per gallon) throwing in the cost of the car and oilchanges we get pretty much the same price as today's EVs.
Thus the bottomline is, gasprice has to triple (mind you that is not the same as oilprice) so the EV would be the same overall cost as the cheapest American car...(I know I simplified it a bit, but you get the picture)
One could make the Mad Max argument, that you will get economic halt and social unrest before the EVs take over...

Well, suddenly you threw in hybrids too, but sure for fun, deal...
By the way one thing that brought down oilprices from $140 per barrel was that the world simply couldn't pay that much for gas, otherwise known as demand destruction.
It could and probably will happen again, that as gas prices increase, the demand's drop for it will limit the price going above a certain level. It will reach a certain equilibrium where cars will be used only for the absolute necessities, like work and food transfer...
But that will also slow down the spread of EVs...

I threw out hybrids (from my side) because I expect they will all be considered smoker junk too in 10 years- anything with a tailpipe belching stuff we can't breathe or drink. I'm keeping fuel cells on my side of the bet, because they are in effect chemical batteries, charged with sustainably-produced pressurized gas. If you want to rule out CO emitters, I'll have to extend the bet. But simply that a majority of private (not public, that's too soon/easy) ground transportation will be electromotive by 2020, that's my bet with you.
If you have a lawn, buy a cordless electric mower and you will understand how much less a PITA it is, and how much cheaper, to just plug in torquey workhorse things instead of filling them up with pricey, smelly, hazardous, toxic liquid gasoline. It's a no-brainer now, and in 10 years... well, "duh".

The question is not whether electric cars will ever become common, standard vehicles on the road.
The more interesting question is: if not, why not. They have several important advantages over IC vehicles (and even over theoretical EC hybrids, an ideal employment of Stirling cycle engines), and if these advantages cannot find their market, that's worth asking about.

Want to buy a Leaf or eMini in the first run? Can't- the market is completely sold out. Many people understand that batteries and performance are going to be highly upgradable over time, without need for changing the motor-generator wheel hubs and controllers. What other major mechanics to build and maintain (besides basic suspension and collision protection) are there? Not much at all, and much less to build and maintain than in a smoker. There will be at least 100,000 PEVs on the road in 2 years, and something highly exponential after that.
