"I'm not robot" very big irritations

Am I the only one with so much trouble getting past the 'I'm not a robot' pictures?
It's driving me crazy to click for dozens and dozens of trains, busses, traffic lights, motor cycles, stairs.... A few times I give up, I don't understand any more what Google want from me, very irritated!
What's the point of irritating the user in such extend?? There must be a more user friendly method....

you are correct, it is nuts; I tried to find the CAPTCHA web site and there is no way to communicate with them, or whomever else designs this.
it is nuts to have to go through 3 or 4 screens of pictures..
