I want a device that will not control the car but will give more a ton of real-time information, ideally projected on some corner of my windshield.

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.

> 1. Speed limit for the area/road I am in.

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.

Yeah I think Satnav answers most. I guess the biggest thing we are missing is Lidar hooked to Satnav

Most satnavs have it already.

Partially...

- 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

> 1. Speed limit for the area/road I am in.

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.

>3. Information on common accident types in the area I am driving in.

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

sligthly similar in spirit.. I so wish I could have local information about stop lights..

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)
