That one already exists, many manufacturers already provide 'intelligent speed' systems, which combine gps and traffic sign recognition camera info to determine the current speed limit in that stretch of road and display it on your dashboard.
- Satnav, is based on GPS which has a degree of error, it might place on a 4 lane road or a 2 lane road immediately parallel to it, with a drastically different speed limit.
- Satnav has no way of adapting to temporary lane closures or roadwork speed limits.
That's the reasoning for combining GPS with TSR camera data, in these 'intelligent speed' ADAS systems.
Waze is pretty good at this, presumably because the road/map data is crowdsourced
My 2018 Honda Accord uses the camera to read speed limit signs and displays them in both the heads up display and in the middle of the gauge cluster.
Then I use Google Maps with CarPlay to offset some of that other information. It will alert if an alternate route becomes faster, or a wreck is ahead. I've also found it's been pretty good to know about road closures as well.
I think this one is incredibly important. Although drivers/AI need to maintain an adequate level of preparedness for general situations... cities and police departments have historical data for accidents. There should be notifications about specific things to look out for. Net-net this might actually reduce accidents
I like to play the 'continuous driving' game where I coast in neutral if the next light is red and try to get the green light so save kinetic energy etc
With this data I could compute the avg speed required to do so (granted there are other factors because I don't want to clog the traffic too etc etc)
Computers assisting but not supplanting people's natural abilities is one of the utopian visions of how to use technology. GP's idea seems brilliant and the only downside is that 2020 has shown that lots of stupid people would proudly boast how they ignore the warnings or pump the statistics in the wrong direction. They would probably get a catchy name for themselves too.
Our brains are kinda specialised to process information at that speed, not at cars speeds.
Having an augmented reality is definitely useful, the same way it's useful for you to have access to maps with realtime location in your phone while walking in the city. Why don't you use your brain and navigate solely through memory? You could still do it, why use a smartphone for navigation? Because it helps.
The same is the case for augmenting information you have, in a car it can be quite useful if you end up missing a sign for the maximum speed (as I've done through Germany in some Autobahn stretches that change speed, most of the times due to construction). The same is the case of giving more spatial awareness through data, who is around you? That is the most basic skill you need as a driver, if there are systems to feed you this data in a quicker and more processable way rather than relying on other people's ability to maintain their attention to be checking their mirrors and keep awareness of their surroundings all the time, so be it. I do it all the time while driving, I don't trust others do the same.
So you know, you could also use that brain a bit more.
The idea suggested is interesting. Some of it I solve by a regular navigation app. But looking at this screen on my right may not be the ideal experience.
Information including:
1. Speed limit for the area/road I am in.
2. Real time radar report telling me how many cars/pedestrians e.t.c are around me.
3. Information on common accident types in the area I am driving in.
4. For my corner of the world, it will be good to get a report on road status before I take the route - something like gravel, cratered e.t.c
I suspect that something like this would sell like crazy for existing cars. Basically a thing were I install a camera/sensor that is hooked to such a device.
