I don't think that they will rely to much in the radar technology, I think this is just a patch until the cameras and AI will be advanced enough to take over entirely (that if ever the technology will be safe enough to be adopted on a large scale).
Just imagine that you could silently blind all cars around you. The hacking resources will be unlimited. What can you do to stop some somebody to do that ?
Of course you can blind a camera or even the driver to but he (or the passenger) will know that and take action.
A short failure of a CDMA or Wifi network can pass unnoticed. A car cannot wait one second until it gets data again, the requirements are much much higher.
Actually I don't see a future of the self driving. Many "smart" devices are making our life less secure and less private day by day.
I think that in the end there will be some centralized driving , rather smart roads that will guide each car in the traffic.
Apart from that, I see many disregarding the power of the image processing even I don't think the cars will ever drive using only cameras.
In the first place a camera has a huge redundancy. I don't see how an insect eye can better than a human eye.
- "The radar can read the speed"
The camera (one or more) can also read the speed of an object. In 3 directions.
- "The radar can read the speed with a great accuracy"
I'm not sure about this point. I really can't tell the speed without looking at the speedometer (which is not accurate at all) and I'm still driving well.
- "Cameras can't see in the fog"
It's true. Then drive slow through the fog. A pedestrian or a dog also don't see in the fog your smart car approaching.
It's hilarious how CDMA or Wifi is given as example of sharing the same bandwidth for a car radar. Are you using Arduino to run your ABS?
Pushing ahead the smart driving cars is more a marketing move, It will not make the streets safer in the near future and the driving skills of the people will get lower and lower, I don't even know how this will work, you won't need a driver license, the car will get you everywhere?
I also see in the Marcus Brown's document linked by Marcus Muller how the smart cars will nicely and honestly cooperate into avoiding obstacles and also sharing the radar bandwidth. What a wonderful future!
That means that a Russian hacker car could make my car jump outside the road at 100 km/h as a better option than hitting a wall that only he sees?
