You all must have some high powered Are Vees there!
I can feel a brake hanging up a little on a trailer behind a diesel pickup, but there are folks who can drag a car down the road in park or with the brakes locked up and not notice anything is a bit off??
If that's the case, you only need to look in the mirror to assign blame or fault. Wake up!
I've said it before, driving or towing a large vehicle or trailer isnt in everyone's bag of tricks.
I'd never attempt surgery or computer programming and some people shouldn't tow things.
