There was talk of embedding sensors in the roads that the auto-driving cars could track... Like Bots' Dots but with RFID tags in them... I figure that would be a maintenance nightmore though...
RFID tags seems like an odd choice. They have such a limited range. It feels like there would be a material that is extra easy for sensors to detect, and could maybe carry a small amount of information.
Probably, but really when it comes to driving there just needs to be an encoded lcoation in it... Hell three-words is all you need to mark any spot on the map to within 10'...
and what they really need is enough range to detect the last one, the closest one, and the next one...
There are a lot of ways to do it....Cameras and GPS are not it.. I won't go near any of the current incarnation of "Self Driving" pieces of shit... 40 years in IT and I know enough about computers that I don't want one making real decisions for me.
Yes like an rfid tag for example
you could also maybe make the cars scan street signs to tell their current location? these street signs largely already exist as human drivers have to read them too.
Character recognition takes a LOT more processing power than reading an RFID tag.
hence the QR code suggestion, it also wouldn't depend on rfid tags embedded in the road surface that would get worn and damaged and needs replacement way more frequently than a sign with a QR code.
But cars already do that, for speed limit signs and such
Not really. Most of the cars that display speed limits do it by retrieving data from an online source. I don't think any of them actually read signs actually.
A 5 sec google search: the ford fiesta manual says snow/rain covering the sensor under the windshield might make it miss signs.
Interesting. Well that's terrifying. A little spray point and I can make an 85 mile an hour zone!
? The driver is in charge of driving, the assistant is just that
That's now how the owners of all of these 'full self driving' cars feel ..
I've worked with computers long enough to never EVER want to trust one to drive.
Pretty much fuck any car that's connected to the internet...
