nothing, as cars will be relegated to the super rich, and the ohers will have just have to use electrically powered public transport (probably hydrogen fuel-cell type)

[QUOTE=Tezzanator92;32446965]I think we should have standard electric vehicles with much, much smaller batteries that take their power from the road in some way. I drew a design for this road-power-pickup system that could be easily retrofitted to existing road but it does need some refinements.
The small battery would keep the vehicle powered for short periods of disconnection.
Why carry around a heavy power supply when you can skip the whole inefficient Charge-Discharge step altogether and cut down the weight of the vehicle??[/QUOTE]
Dodgems?
Pretty much, just a bit less obtrusive (I'm thinking a road surface dotted with electrodes and intelligent electrical pickup points in the tyres - Whether the current handling of such a system would be great enough to power a car is something that would need to be looked into maybe... Small scale tests!)
[QUOTE=DainBramageStudios;32442039]Do you not have any clue how thermodynamics works? What you're advocating is using electricity to split water apart into hydrogen and oxygen, then use energy to package that hydrogen up into cylinders, then energy to transport those cylinders around the world to be used in cars, which then burn the hydrogen to get less energy back per mole than was used to create it, rather than skipping the middleman and using the electricity to just power the fucking car.
Your system is less efficient however you spin it. It doesn't fucking matter that you get the water back - you use way more energy than is needed.

This is exactly what I'm talking about.[/QUOTE]
Hydrogen is much easier to store than electricity, especially with the nano-tube sponge tanks which are being developed

How about making roads have a groove down the middle and two metal rails like a scalextric track? That way it would reduce crashes aswell because you wouldn't have to steer so much.

Hi, I'm electric engine, and I am better in every conceivable fashion to an internal combustion engine. I have almost no moving parts and my power curve is a straight line followed by a very mild descent that STARTS at the top and exceeds your abilities pretty much across the board. I am capable of generating so much torque that I can snap axels easily and require electronic controls to mitigate my acceleration down to a level sustainable by the frame of the vehicle. I am several orders of magnitude more efficient than an internal combustion engine and require almost no fluids to continue operating.[/QUOTE]
The fact that electric engines don't go vroom-vroom is enough reason for me to not buy one. Instead of a throaty roar, you get a high pitched droning noise. Batteries are crap because they're heavy (Nissan Leaf: 3500 lbs, more than the fairly large Honda CR-V which is 3300-3500), current batteries take ages to recharge, and even the proposed extremely fast charging stations take something like an hour to fully charge up a car. I'd rather have a hydrogen powered car over an electric, because combustion engines for both gas and hydrogen are close to identical in most regards, and they are both lighter than electric.

That would probably require obscene amounts of maintenance, considering how fast cars go and how many cars would be using it.

like a tram?
but then how would you off-road, and also there would the problem of maintenance, and lane changes
However, if there was eg a strip which could be used for charging, which you could go off of to drive normally

No doubt they would zap some pedestrians. What I think could be really beneficial would be strips on highway only, people only use local roads for short distances.
