You can keep your self driving cars, I like driving.

And why does this vehicle have wireless access to it's control systems?

could be for something as innocent as updating maps in the gps system which need to be kept up to date so that new roads or old roads can be added/removed, what they said in the video is they used their exploit to get into the system then move laterally around to see what systems are linked together to send them commands, just down to shoddy programming basically.

There are other reasons to have a internet connection: to check traffic conditions and weather prediction.

For example. let's say that you leave work on one of those self driving cars, and there are 3 routes to go back home. The car connects to the net and finds that there's a traffic jam on the first route and that a storm is comming, making route two more dangerous (because of floodable parts of the road, for example), leaving route three as the best option.

That shouldn't be handled by TCP tho, if they just set up transmissions of information to go 1 way and not set up a connection to the cars then the GPS could simply tune into the broadcasts coming out and never reply with information about the car back to the sender, that was what these guys exploited.

Think of it like this you can have interference come in to your car stereos radio signal, but the car radio will never be able to broadcast back an acknowledgement to the interference to give the interfering channel information regarding what car stereo it has managed to interfere with and in these guys case information about the complete car OS they're communicating with.

Hopefully they will now make the signals to only go one way, and find a way to identify and block unwanted signals.
