And what exactly is the lifetime of a car? And is this the lifetime of an electric car, or any car?
From the context, the Dutchman is referring to the lifetime of an electric car. The lifespan of an electric car is basically determined by the lifespan of the batteries, so of course the batteries are going to last the lifetime of the car, by definition.
The life of the car is however long the battery lasts. It's not economical to replace them. So he's right, the batteries last for the lifetime of the care because they are the fundamental limitation to the lifetime of the car.
If this "EV researcher" is trying to make the case that current generation EVs are perfect than he's a clown. These are the equivalent of those crappy CFC bulbs with the curly glass that sucked hard. Real bulbs were banned, we were stuck with those. They didn't work when it was cold, they lasted nowhere near as long as was promised, the light was cold and ugly and everyone hated them. It was terrible tech. we needed a proper low energy bulb and that wasn't it. LEDs came along and now qw have a real alternatives the incandescent bulbs. EVs need to evolve too because this current get tech is not good for all the reasons Mr. Bean states.
