Do driving examiners judge the test takers?

So the other day I have failed my driving test for the second time. I have taken 23 lessons and have done over 50 hours of driving with my parents. On my first test, I failed because of my fault (I repeatedly didn't look in the mirrors) . I have had my second attempt two days ago and this time I ended up with only 3 minors and a serious fault. The serious fault was the following. I was driving on a busy road behind a commercial van, and I saw the warning lights come on on the back of the van so I eased off the accelerator. The van wasn't braking gradually but instead it left braking for the last few meters. So as soon as I saw the brake lights come on, I was braking too, but the examiner says that I was braking too hard ( I was braking at the same rate as the van) and says that the car behind me COULD have crashed into me, causing a collision. I just don't understand why he had to fail me just because the driving behind me wasn't keeping the following distance. I'm NOT COMPLAINING AGAINST THE EXAMINER. I respect their experience but both me and my instructor's feelings is that maybe they judged be based on my nationality and the car I showed up to the test with. I own a 2L Honda accord and I think that as a 17year old boy they think that I may be a liability on the road. One of my family members died in a car accident so I'm not the speeding type of guy. Do I stand a better chance if I take my instructor's car? Will they look at me differently?

Yes they judge you.
They judge whether or not you're a safe enough bet to be let on the road on your own and you're obviously not yet there. Get rid of that chip on your shoulder and stop trying to invent excuses why you failed, get over it, polish up the areas that need attention and try again.

You were too close to the van. So close you could not see what was happening in front of it and had to rely purely on it's brake lights which meant you could only react once the van had already reacted. A little further back and you would have been able to see around the van and start braking before it did.

It's nothing to do with nationality or even what car you turn up in, you could turn up in a Rolls Royce, but you must demonstrate that you can handle it safely without putting yourself or other road users.

Yeah i think they do judge you, i hated the whole thing! I got my license in uk finally at 28yrs old.
even though i was just as good driver when i was 18, they did'nt pass me because they judged me.

i think the whole system of driving licenses is against human rights,
ssome people just don't have anyone to get them their license.

It's all BS, I know of an instructor who is told to fail everyone and another one is told to pass everyone.

Your nationality? Get off it. That race card thing is way too overplayed.

Here's how it works, one serious fault during the test and you fail. Just one, that's all it takes. Whether you're a 17 year old boy driving a Honda Sniffle or a sweet old nun driving a slow minivan, if one serious fault happens it's a fail. Sudden braking in heavy traffic is a serious one.

You didn't do anything 'wrong' when you did that, you just made a common (but still dangerous) new driver mistake. It could have happened to any new driver, but it did happen to you. That, not your vehicle or your nationality, is what caused you to bomb the test.

If your driving had been textbook-perfect and you still failed, then maybe. You could blame age / vehicle / nationality prejudice on the examiner's part. But that's not what happened, so there's no use what-iffing about it.
