Checked how? To your own opinion or to a universal standard?
Basically giving you a hint, it would need to be checked in a way that can be documented and replicated. So that by and large it isn't based on an opinion of the tester. This is where it is very difficult, because many historic cars simply do not meet anything that would acceptable in terms of documenting it. You would then need loads of different grades to rate a vehicle on based on age and construction type.
This was largely the issue....
You cannot realistically test brakes like this to the same standards as modern ABS discs...
Dismiss no, but most of your crib sheet will say either n/a or exempt.
I think the clue is in the 'garage I worked for specialized in classic cars', people hardly are likely to take perfectly working cars into a garage are they. It's a bit like saying you only ever see sick people in hospitals!
The legal requirement for the car being road worthy has not changed. And nothing prevents any owner having their car inspected.
It does matter completely. All things in life are risk based. Driving any car or walking down the street carries risk. But it is generally low enough that most people will do it. Extreme sports carry much more risk, which stops some people wanting to partake, while others will refuse to do anything so risky.
By the numbers the chances of a historic car being involved in a serious RTI are so low that most people would likely deem it not a risk at all.
BTW - tractors don't need an MoT, either new or historic. Apart from you place or work, you and most people are likely to see more tractors on the roads more often than historic cars.
Clearly you aren't grasping the above point then. Which really makes the only thing look a little stupid is.... . y.....
