That's a bug. Relax. It'll get fixed.
Don't be all pissed at Tesla because some people have continued to demonstrate they can't be responsible drivers, thus endangering others, getting into accidents, and in one case killing themselves because they aren't using AP properly nor paying attention.
Let's all take a deep breath and engage our brains. As adopters of new tech, tech that's leading us into a world of autonomous driving and a ride sharing autonomous network there are going to be hiccups along the way; bugs in the system, trials and errors, regulations and laws of the road that are going to limit the system for a time until they have been changed and so on. Pissing in Tesla's cornflakes isn't going to get you what you want and it only makes you look like a child having a tantrum. Demonstrating that all can be responsible and use the system properly until the system is perfected and the rest of the world can catch up is what's going to get it here. In the meantime, report system bugs and the like to Tesla so that they can continue to work on AP, prove to the likes of NHTSA that it's safer and get universal regulations changed and standardized etc...
This may come as a surprise to you, but when autonomous driving gets here, there won't be any more driving 70 in a 55 zone and thinking that's okay. So enjoy speeding on public roadways while you still can. The law to go with the flow of traffic was never meant to encourage speeding and you know that.
In a future of autonomous driving it's quite possible that there will be designated highways that require a vehicle have autonomous capabilities to even get on it and on those roadways the speed of vehicles will be even higher because at such time it'll long since have been proven that computers are better drivers than people.
