Already tried it. There's a simulator in XCode that does exactly that. And it makes for a terrible user experience.

What Apple are doing now is the right approach for user facing apps. Make iOS apps compilable for OSX, but allow for changing the things that are different on the desktop OS. Like resizable windows, typing and editing with a real keyboard, target sizes suitable for mouse pointer rather than finger, different transitions, a menu etc.

Yeah, that must be it. There's something you understand that Tesla doesn't. They should hire you.

"The hardware needed". They don't say they have the software for it yet.

But there are mountains. And tall buildings.

First there was cruise control. It maintained speed.
Then there was adaptive cruise control. It maintained speed and distance from the car in front.
Now there's autopilot. It maintains speed, distance from the car in front, follows lanes and assists with overtaking.

At no stage did anyone say you could take your focus off the road with any of them. And there's no need to revert to older technology because some people are stupid.

Neither has Slashdot.

This is a silly meme. There's no evidence whatsoever that people driving Teslas don't know that autopilot is an assistive technology, not one that drives itself without monitoring.

Sure, some people have done stupid things to override the failsafe that checks for hands on the steering wheel. And some have even then got into the passenger seat or even the back of the car.

But they've done this in spite of knowing what the autopilot system does, not because they are ignorant of it.

There are plenty of things that are free. You (and others of your political persuasion) just don't know what the definition of free is,

It applies to all users.
Apple computers and software just tend to be better designed.
The tendency with Windows and Linux is for programmers not to ever rhink and make decisions. They offload all decisions to users, and end up with baroque software that is difficult to use.

A default doesn't take away the problem of too many options for users to find anything.

Generally speaking, options need to be fought against. They need to justify the real estate they use. This wouldn't.

Sure there is. You could have options for everything. But the more options you have, the harder it is for users to find the option they want.

In this case there's no good reason to hand the decision over to users anyway. Almost none will be interested in changing it, or even be aware that there's such a feature or what it's for.

Tesla aren't using GPS as an input to steering. They only use it to mark out regions where Autopilot is/isn't allowed and speed limits.

Who said anything about construction companies making complex GPS maps? There's nothing in my message that implies that. I guess you didn't understand it.

You are making assumptions too.

Sounds like a Wile E. Coyote trick.

At some stage autopilot will start taking input from GPS, just as I do at night on a dark road, to see ahead for any significant bends in the road to be at an appropriate speed, and be ready to turn. With GPS getting more and more accurate, autopilot would perhaps see the difference between the road markings it can see and the GPS track, and slow right down.

Why didn't it see the barrier? One online theory is that there was another vehicle in front that wanted to make the turn onto the off-ramp, but wasn't in lane. So it wandered into divider area, whilst finding a gap in the off-ramp traffic. And the Tesla followed it. And that the other vehicle pulled in at the last moment, leaving the Tesla suddenly faced with the barrier.

We do know that a human might easily have made the same error, as the safety barrier was destroyed the previous day by another driver. Poor road layout.

In the UK, that area would always be cross hatched. Always. So no one could mistake it for a lane.
