Autopilot can be active at any time. It's especially good in heavy traffic. Works well on two lane roads as well as highways.

I said it was only really designed for highways. Not that it can't do other roads.

They compared accidents driving with AP ON vs AP OFF.

You are completely wrong. Consult the report. They compared cars without AP installed vs those with it installed. Using the data for cars with AP installed, regardless of whether it was active or not.

You don't win an argument by claiming the other side is confused. I have actually consulted the original document so I know EXACTLY what they measured.

You claim "the earlier time period where more people were abusing the system". Yet they can't have been abusing a system that they didn't have because it was not installed.

Again, the NHTSA know what they are doing with automobile safety statistics. You, have less information and less ability.

No they didn't. The statistics cover Teslas without autopilot vs Teslas with autopilot. The second group including all miles, whether or not autopilot was actually engaged. This is because:

a) Some of the safety features of autopilot are on all the time even when the full autopilot isn't engaged.

b) If they did what you suggest, they'd be comparing mostly urban travel vs mostly highway travel. As autopilot is only really designed for the highway at this stage.

The 40% reduction is of all Teslas that have Autopilot enabled. Right from the first day. And it covers all miles, whether autopilot was enabled or not. (Several of the safety features of autopilot are always on.)

So to answer your question, change of driver behaviour having heard of autopilot crashes could not possibly have affected the statistic, no.

There is some mild rebuking if you don't hold the steering wheel.

If you don't hold the steering wheel then after a time between 1 and 5 minutes (depending on situation) you get an audible and visual warning. Ignore the warning for 15 seconds and you get a "strike". 3 strikes within an hour and you're out: you won't be able to use autopilot until your next journey.

Comment Re:Exception Handling (Score 1) 339

They are exceptions with some of the negatives of exceptions removed.
1) They don't leak.
2) They are never "unhandled".
This is because the implementation is different from C style exceptions.

But in terms of what the feature is, they are exceptions. You would never put "doesn't have exceptions" in a cons column of a pros/cons list.

Comment Re:Tesla Autopilot development (Score 1) 339

Chris Lattner creates compilers and languages. So that's doubtless what he'll do at Tesla. Tesla has an NVidea board that is built for running neural networks, and does massive amounts of processing with Intel CPUs ARM cores and GPUs. Seems to me there's ample room for a language and compilers to deal with that, over and above whatever NVidia supply. A language for dealling with multiprocessing, neural networks and for creating AI rules. That sort of thing.
