- A traffic light is out and a Police officer is directing traffic. Without a driver, how will the car interpret the Officer's hand signals?
- Your route demands that your car make a right turn on the next street. As your car approaches pending turn, you can see that an accident is blocking the street about 30 feet down the block that GPS has instructed the car to take. If you were driving, you could pass the right turn and take the following right. The computer will take the right and get stuck behind the accident until it is cleared.
- Will autonomous cars be able to see road hazards like, large pot holes (that can break an axle) and potentially injure the passenger?
- Road construction removes the white lines from the road on a three lane highway - how will the autonomous car stay in its lane?
- Sun glare blinds the optics or, a plastic bag flying around in the wind, or a sudden snow storm covers the car's sensors.
- Passenger passes out, has a medical emergency and is unable to speak. Will the car realize what has happened and go to a hospital or, simply make its way to the final destination and when the passenger doesn't exit the vehicle, will the computer finally call for help?
- Changing lanes on a LA or NYC freeway will be a challenge especially, during rush hour when no one lets the computer car change lanes and no one lets the computer car move over to get to an exit ramp.
We are a long way off from safe, autonomous cars.
Most of these things humans aren't great at doing either
For #2, the idea is all the driverless cars operate as a neural net (AI) and you have near real time traffic info and routes can be adjusted automatically (like the traffic prediction on google maps or waze). This also helps with point 1 and 4.
For #3 they can and have implemented IR and thermal cameras... snow/dirt/glare become much less of a problem. No worse than running out of wiper fluid or driving into the blazing sun with a dirty windshield, definitely better than the 85 year old grandma with cataracts
Medical emergencies - meat drivers can't do this either if the driver is the one in trouble. They could easily integrate with smartwatches/fitness trackers and detect such issues.
RE merging - Elon, uber and co want it to be illegal to drive your own vehicle. If all the cars are AI driven they can reliably merge at speed with little more than a car length between them.
Most of these things humans aren't great at doing eitherYou just supported my view... if humans aren't great at driving their own cars and humans are the ones doing the programming, double fail.
For #2, the idea is all the driverless cars operate as a neural net (AI) and you have near real time traffic info and routes can be adjusted automatically (like the traffic prediction on google maps or waze). This also helps with point 1 and 4. Current traffic predictions are fairly decent but, what about an EMS vehicle or a garbage truck that is blocking the street - which is what I was talking about. These temporary road obstructions are not reported on Google Maps or Waze. A human would take the next turn, the AI will sit behind the temporary road block until it clears.

Hey, I'm all for AI cars but, the majority of drivers are not 85. I suppose AI cars would also be equipped with windshield and sensor wipers and may have a better chance of seeing clearly especially, during adverse conditions. But, would the computer be able to interpret fuzzy sensor readings as well as a human looking through a rain covered windshield? Maybe, maybe not... computer recognition is good but not flawless - insurance companies will not cover "good enough".
Medical emergencies - meat drivers can't do this either if the driver is the one in trouble. They could easily integrate with smartwatches/fitness trackers and detect such issues.I wasn't talking about a Driver having a medical emergency (a valid issue nontheless), I was talking about the PASSENGER having a medical emergency. Passengers are not going to hook themselves up to smartswitches/fitness trackers just so the car's computer can tell if they need help. You will probably say, "they can put them in the seats" but, will the passenger's health data then be sold to health insurance companies?
I'm all for AI cars...I'm just trying to point out that there are thousands of issues that the computer will not be programmed to handle... simply because, not every issue can be planned for - a human can make new decisions with both good an bad results but, without programming, a computer will either freeze or, make a bad decision.
RE merging - Elon, uber and co want it to be illegal to drive your own vehicle. If all the cars are AI driven they can reliably merge at speed with little more than a car length between them.Of course Elon, Uber, Lyft, etc., want it to be illegal to drive your own vehicle... then, everyone will be forced to use one of theirs. AI cars will be more expensive and fewer people will be able to afford one - if human's driving becomes illegal, less wealthy people will be forced to take a car service. Not sure how well that will go over.
Of course, prices will eventually drop but, you can bet that the car services will do everything in their power to prevent people from owning their own AI cars and force them to use their app to call a car.
If every car on the road were AI driven, in theory, things would be safer and we would have less traffic... I'm all for it.
In their eagerness, Uber and Elon Musk will put AI cars on the road before they are ready and there will be more crashes and fatalities. The are not nearly ready, as proven by the recent crashes and insurance companies will be against them until it can be proven that the programming is absolutely flawless.
I have no doubt that AI driven vehicles are going to happen, I just don't think it will become mainstream for at least another 30 years. Technology has had rapid advances but, programming for unexpected events is what will slow things down.
