This is a really bad presentation - the content is good but presented in a really bad way. Also, the tesla buildroot does not contain connman which is the network daemon in which the vulnerability is identified, but it is shown that the you gotta clone the buildroot from tesls for part 1 of this. It would be great if there was a little background info on what you are trying to do - Please record screen and include in the video next time - camera view are not good for virtual demo's.
