So by-wire means that a computer, or an array of computers, what we call ECUs, runs the vehicle and not mechanical connection. So in today's vehicles, in all of them basically, almost all of them, for example, the steering wheel that we hold is connected mechanically through a rod to the wheels, and by turning it, it might be power steering, etc., but there is a direct connection between our hands, basically, and the wheels themselves, and we literally turn them mechanically. Brakes are the same, and so on and so forth, and it's been like that forever. The problem with that is that it has a lot of limitations, mainly around changing dimensions, mainly around efficiencies, because we've reached the point where computers can run faster calculations, faster than us, more accurately than us, and therefore becoming safer. But the ability to do that today is very complicated. Because if you think about it, there is something called a by-wire car for years, it's a remote control car, right? You just move it and it moves. But there's what industry calls no redundancies. Think about an airplane. The by-wire basically started in airplanes back in the day. The helm, the joystick, used to be mechanically connected through cables to the flaps. In today's airplanes, there is a computer and an array of actuators, motors, that move the flaps. But what happens, God forbid, if you're flying across the ocean and one of your engines shuts down or breaks? The airplane is built with enough redundancies to be able to fly only with one engine and to be able to operate different hydraulics, etc. When it comes to vehicles, it's even more complicated. Why? Because airplanes cost hundreds, if not tens of millions of dollars. They're being operated by very highly skilled people, co-pilots, and even when the pilot is encountering some kind of problem, there is ground control to help them get through that. When we drive our vehicles, we just want to get from A to B. We're not trained in any mechanical way or any special training to operate the vehicle. So the vehicle needs actually to be far more reliable, and even if there are malfunctions, to be able to operate. And this is where the industry struggles, because when something happens to by-wire, as an example, what happens if you lose power to the computers and suddenly you don't have computers? You can't afford the car, the vehicle, to stop, or actually even worse, not to brake or to accelerate, and so on and so forth. So you need to create an array of computers, an array of actuators, motors, that are able to control the vehicle in a safe manner where there is not a single point of failure. There's not a single incident that causes that vehicle to put you in harm's way. And that's by-wire. So we've created a technology that we call the X-by-wire, which means all steer, brake, and drive, that is designed around six ECUs, six computers, that control the entire vehicle. Now think about it, in today's regular car, you have tens, if not more than a hundred, small computers that run everything from your power windows to your steering wheel to your air conditioning. We decided to aggregate them all and use only six, but those six are built differently, far stronger, far more reliable, far better. So for example, you mentioned we have corners, so we put all those in the corners of the vehicle where the wheels are, and if one corner doesn't work, the other three can take over the vehicle itself. Even if two don't work, the other two can compensate, and we have all the redundancies to be able to be allowed to go on the road, which is called certification. We can meet all the regulatory and safety requirements to allow us to go on the road.
