Personally, I'd love to be a traffic officer, not even for the driving fast, just hate when I see something that is dangerous
ABSOULTELY how I feel. I saw some idiot overtaking a row of cars the other day, must have been doing 60mph in 2nd gear, on practically a blind bend in a residential 30 zone with little kids walking to school close by.
I wanted to drag him out of the car and throw him against it and ... GRRRR!!
I managed to catch his number plate, and I took a picture of him on the wrong side of the road overtaking on the bend...I've been half temped to show it to the law..

But there is the satisfaction of stopping them and giving them what for.
I am sure with something like you described you could do them for dangerous driving, so 3 points + £60 fine.
My pet hate is mobiles and no lights on when its dark, amazed at how many people don't put their lights on in poor conidtions or leave side lights on when full is required.
Good news from Hotel21 about petrol heads, i am sure it would be a bonus in the interview if u said "i love driving"....
