  4. Great video and wonderful example at the end. Brakes don't stop cars, brakes act on the wheels to stop them, so as to cause the tyres to stop cars. Pedantic of me, but it's important to remember the stresses that tyres go through in cars and the importance of tyre pressure and maintenance. (And thanks to your friend the Humble Mechanic, his video helped me change a wheel on my VW with that funny jack).

  5. Ken Tyrrell, the Formula 1 team owner, said once 'Never underestimate the importance of those four pieces of rubber'. Certainly in racing it's a lot more important, but tyres are what enable your brakes and steering wheel to work. Here in England, winter tyres are rare, but they make an immense difference when the snow starts. The downside, that minus 28 feet stopping gives you a lot more scope to have the guy behind help you on your way.

  7. 10 years and a day before this, you did a short vid about octane ratings and mentioned altitude's effect on octane at around 2.10.

  8. Ken Tyrrell, F1 Team owner in the good old days said 'Never under-estimate the importance of those four bits of rubber' (although he used 6 sometimes).

  9. Look at F1 racing, forever squeezing margins out of engines.

  10. The politicians will go for batteries in trailers towed behind electric cars (reducing speed too), and they you stop at a station and swap trailers.
