Sure. But that's not the kind of thing a IoT hacker would consider a success. Someone might be content, however, with making a mod for Tesla that can e.g. follow "complex" paths of bright orange cones in a parking lot. Test it there, without being in the car themselves and put it on GitHub for bragging rights of having made a cool AI+Systems project. The problem is then someone might see that "cool hack", think it is more than it really is, and kill themselves turning it on while on the highway...
