May be an image of car, snow and road
Electric cars – the biggest scam the world has ever seen?
Did anyone think of this?
“If all cars were electric…
And if we were stuck in a three hour traffic jam in the cold of a snowstorm, the batteries would completely die.
Because there is basically no heating in the electric car.
And the fact that I am stuck on the street all night, no battery, no heating, no window wiper, no radio, no GPS, the battery has been dead a long time ago.
You can try to call the ambulance and protect women and children, but they can’t come to help because all roads are closed and probably all police cars will be electric.
And when the roads are closed by thousands of parked cars, no one will be able to progress. How to charge batteries on site?
The same problem is that there are kilometers of traffic jams during the summer holidays.
It would not be possible to turn on the air conditioning in an electric car for a short period of time. Your batteries would die in an instant!
Of course, no politician or journalist is talking about it, but this will happen.
