Tesla parts are made in China, including computer parts. That means Chinese could hack any of those computer parts. I don't know what parts they have access to now. From Tesla suppliers start to see higher volumes from Model 3 production ramp up: We have to assume that any computer part is hacked already, and could be taken over for any purpose, including killing occupants or other people on the road. The exception would be any part made in-house by teams that are not infiltrated and doesn't contain any subordinate parts made elsewhere. These days, that's very hard. I think this problem affects most if not all modern car manufacturers. I don't think any of them care enough to fix it directly; I think they just assume it's not their problem, and consider it something that doesn't materially affect their financials.
