I’m thinking a self driving car is essentially a robot driving cars, right? AI, robots, computers - all the same thing, true?

So I have a question:

if one of the tests for spotting robots - you know, those captcha tests online (find the bus, find the motorcycle, find the steps, find the traffic lights) - well, if a robot wouldn’t be able to find the traffic light in a captcha test, how are they gonna do when driving a real car?

I don’t mean for you to lose sleep over this - but I was up all night thinking about it.
