It’s definitely debatable, and is unlikely to be a primary factor in a significant number of events. It’s also hard to measure because the data is pretty bad.

As an example, your tire could blow out and cause you to hit a drunk pedestrian. It would be flagged as an alcohol related crash. Police are mostly interested in violations and liability, and you are responsible. Unless it’s a fatality, nobody will even ask if your failure to stop was related to poor brakes or bald tires.

In my opinion, the only clear stat is how many people are dead. Everything else requires domain expertise to interpret.

Yeah and those stats show a big difference. In the UK there are 2.6 fatalities per 100,000 population on average per year. And in the USA it’s 14.2

That’s five times higher!

For those that don’t know these are all the checks done yearly to every passenger car over 3 years old. https://www.gov.uk/government/publications/car-parts-checked...

The UK also has much stricter training requirements prior to being granted a license, among other differences. I don't think we can pin all the differences on the yearly MOT.
