The day that EV manufacturers design an EV that looks like and performs like a
real car (and sells for a price that competes with a real car) is the day that
they'll start doing serious business.
Until then we can all laugh loudly at their 'clown cars'.

Well this one will do up to 120 km/hour, is capable of doing 3,000 km
without refuelling and should be able to bring your fried Plaice
dinner, with pancake dessert back from the supermarket.

One of my favorite concept car that is not so clown looking.
" The Eco Speedster, with its surprisingly diminutive 1.3-liter
ECOTECH CDTI, tops out at 155 mph and clocked an average fuel economy
of 113 mpg over a 24-hour road test. A combination of low weight (660
kg/1,445 lbs), minimal drag, mid-engine design, and a 5-speed
automatic transmission let the Eco Speedster rip and sip at the same
time. "
The Eco Speedster appeared at the Paris Auto Show in 2002 and has been
featured in the Discovery Channel's FutureCar series

I did a google for "road horsepower" and the first link was for a
Toyota MR2.
http://www.mr2.com/MR2TechData.html
A test by Car & Driver put it at 14.0 hp @ 50 mph. That would be 14*.
746=10.444 KW, which is what would be needed to cover 50 miles.
10.444/50 = .20888 KW hr/mi. An efficiency of 85% would not be
unrealistic and would give .20888/.85 = .246 KWhr/mi. This thing
looks like it probably has a lower CD than an MR2. BTW that 14.0 hp
was broken down into
Friction and tire losses @ 50 mph ..... 5.5 hp
Aerodynamic drag @ 50 mph ............. 8.5 hp

I think you missed something here. According to your figures, it will
take just over 200 watts to move the car at 50 mph for one mile.
That's not the figure given of 14 hp, that's more like 1/4 hp expended
to move one mile. You have to expend that power at a constant rate of
14 hp or 10.444 kW. Look at it another way.
W=ExI
Where W=watt
E=voltage
I=current (in amps)
To make the math easer, assume you have a 100 volt battery. Then
solve for current using:
I=W/E I=10444watts / 100volts I=104.44amps
We have a constant current draw of 104.44 amps required to propel the
car at 50 mph. That is the reason why it is really hard to get an
electric car to have a reasonable range (200 miles) at a reasonable
speed (50 mph). You would be looking at a total power expenditure of
over 41.7 kW to drive for 200 miles at 50 mph. That figure assumes no
head wind and level ground. Add in real life conditions and you might
be looking at power expenditures of around 45 to 50 kW. Also, you'd
flat get run over driving around here on the highway at 50 mph. You'd
better be traveling at least 60 mph which would boost your totals even
more.
Even if you had a battery that could deliver that much power, you
still have the problem of getting all that power back into the
battery. In order to replace 41.7 kW using your 120 vac outlet, you
need to draw over 41 amps for 8 hours. That is assuming 100% recharge
efficiency.
You can draw your own conclusions regarding the practicality electric
cars.
