Also all fuses in all electronics for the past like, century, have easily replaceable fuses. Basically all the fuses in my car are in a little box under the hood, I could go buy one and replace any in ten minutes.
How the hell is a single blown fuse grounding a car??
This guy: “the brakes didn’t work!”
Your arguments: “brakes normally do work; he didn’t speak to a higher up; the brake lights didn’t come on; he may not be correct about what his back wheels did; he didn’t steer the way I would have”. None of which are contrary to the possibility that the brakes didn’t work. I’m not sure how you jump from A to B here.
It’s definitely impossible to know at this stage whether this incident was caused by the truck or the driver. But there are a concerning number of claims about the failure of cybertrucks’ brakes considering how few of them are actually out there.
