It actually is a joke how bad some tests are. In a lot of cities in Florida your test is done in a parking lot with no real world driving with other cars, and it omits a lot of things, like parallel parking. Ideally licenses should be able to be transferred across states, but tests like the majority of ones in Florida mean drivers from there may be inadequately prepared for driving in some other states like CA.
Still, the US is not the only place with very mixed standards for driving tests. I once heard that the easiest way to get a Dutch driving license was on the Caribbean island of Saba, where you'd get your license if you could drive around the central square without causing an accident. I knew someone who got his license there, and he didn't dare to drive a car in Netherland. Fortunately he had a Dutch motorbike license.
Your comment is ignorant and insulting, since you're basically calling him a liar.
My US driving test was a joke. I pulled out of a parking space, pulled up to a road, took a right turn, drive 100-200 feet to an intersection, took a right turn, then took another right turn into the same parking lot I had just left, then parked. That was my entire driving test.
The original comment never stated that all driving tests everywhere in the US are all a joke. Believing that is ridiculous: the US is a big place and things vary dramatically from locality to locality.
The guy is correct. MY driving test was a joke, and other people have testified their tests were a joke too. Therefore the statement is correct. He never said ALL driving tests in the US are a joke.
It sounds like you're taking this personally, and have some kind of issue because you failed two driving tests.
